Mathplanet offers free high school math courses in four areas: Pre-algebra, Algebra 1, Algebra 2, and Geometry. That scope comes from the site's own description, which presents it as a free, accessible platform for learning mathematics. If you are looking for calculus, statistics, or test-prep material, those subjects are not listed in the available description, so confirm current coverage on the site before relying on it.

The four courses at a glance

The level labels reflect how these course names are normally used in U.S. high school curricula. The site describes itself as offering high school math, which matches this sequence. Exact lesson lists and ordering may differ, so check the course pages for the specific topics included.

Who this scope fits

• High school students who need a structured review or a supplement to classroom instruction in one of these four courses.
• Middle school students preparing for algebra who want to work through Pre-algebra material at their own pace.
• Adult learners returning to math who want to rebuild foundations before moving on to more advanced subjects.
• Homeschool families looking for a free resource aligned with standard high school math topics.

Who should look elsewhere

Because the described catalog stops at these four courses, the platform is not positioned as a full math curriculum. Consider other resources if you need:

• Calculus, statistics, or discrete math — not named in the site description.
• Standardized test preparation such as SAT or ACT math review — not listed.
• College-level or proof-based mathematics beyond introductory geometry reasoning.

How to check whether a topic is covered

1. Open the site and go to the course list.
2. Select the course closest to your level — for example, Algebra 1 if you are working on linear equations.
3. Review the chapter or lesson index for that course.
4. Match the lesson titles against the topic you need; if the topic is absent, the course does not cover it.

A quick way to test fit: pick one specific skill you need, such as solving systems of equations or finding the area of a circle, and see whether a lesson with that title exists before committing study time.

Practical notes

• The platform is described as free, and no pricing information appears in the available site description. That does not by itself confirm every feature is unrestricted, so verify access when you arrive.
• The site is in English, which matters if you are learning in another language.
• Course names follow a standard U.S. sequence, so students from other systems should map topics rather than rely on the labels alone.

Online master's courses in Europe are generally structured the same way as on-campus degrees: you complete a set number of credits (usually 60–120 ECTS), pass assessments, and receive the same degree title as campus students at that institution. What changes is the delivery mode. Programs range from fully online and asynchronous to hybrid formats that require short residencies, and recognition depends far more on the institution's accreditation than on whether you studied from home or on campus.

The main formats you'll encounter

Fully online, asynchronous

All coursework, lectures, and materials are delivered through a learning platform. You study on your own schedule within weekly or module deadlines. This is the most flexible option and the most common for working professionals.

Fully online, synchronous

You attend live seminars and lectures at fixed times, often via video conferencing. This mimics a campus timetable and works well for discussion-heavy subjects, but it requires you to be available in the institution's time zone.

Hybrid or blended

Most study is online, but you attend one or more short on-campus periods — typically a kick-off week, a lab-intensive block, or a final thesis defense. Some programs in fields like engineering, health, or business use this to cover practical components.

Online with optional campus tracks

A smaller number of programs let you switch between online and on-campus modules, or complete the degree online but attend electives in person.

Credits, ECTS, and what the degree is worth

European master's programs use the ECTS system:

One ECTS credit represents roughly 25–30 hours of total student workload, including self-study. A 90-ECTS online master's therefore carries the same academic weight as a 90-ECTS on-campus master's at the same institution.

The key question is not "online or not" but who accredits the program. In most European countries, the national quality assurance agency or the state recognizes degrees from accredited institutions regardless of delivery mode. If you need the degree for a regulated profession, a visa, or a public-sector job, verify recognition with the relevant authority in your own country before enrolling — this is a general rule, not legal advice for your situation.

Admission requirements for international applicants

Requirements vary by country and institution, but online master's programs commonly ask for:

• A completed bachelor's degree (or equivalent) in a relevant field.
• A minimum grade or GPA, sometimes expressed as a class of degree.
• English proficiency — IELTS, TOEFL, or an equivalent, unless your previous degree was taught in English. Some programs accept a waiver or an internal test.
• A motivation letter or statement of purpose.
• A CV, especially for MBA and executive programs.
• Letters of recommendation (often 1–2).
• Work experience for MBA and some professional master's degrees.
• Specific prerequisites such as statistics, programming, or a portfolio for design and technical fields.

Typical application steps

1. Shortlist 3–5 programs and check each one's accreditation and recognition in your country.
2. Confirm the language of instruction and whether your proficiency test meets the threshold.
3. Prepare documents early — transcripts, translations, and credential evaluations can take weeks.
4. Check application deadlines; many European programs have rolling admissions, but some have fixed intakes.
5. Submit the application and any application fee.
6. If admitted, complete enrollment, pay any deposit, and set up your student account and platform access.

How exams, thesis work, and support are handled remotely

• Assessment: written assignments, online proctored or open-book exams, group projects, presentations, and participation. Some programs use timed take-home exams instead of invigilated ones.
• Thesis or capstone: usually supervised remotely via video calls and email, with milestones and a final written submission. Some institutions require an oral defense by video; a few require it on campus.
• Support: academic advisors, library access (often digital), technical helpdesk, and career services. Quality varies widely, so ask current students or check program pages for what is actually provided.
• Interaction: discussion forums, cohort groups, and live sessions. Asynchronous programs can feel isolating if you don't build in regular contact.

Practical considerations before you commit

• Time zones: synchronous programs may schedule classes in the institution's local time. Check whether live sessions fall at workable hours for you.
• Language of instruction: many European master's programs are taught in English, but not all. Confirm the language for lectures, exams, and thesis supervision.
• Tuition structure: online programs are often priced per credit or per year, and may differ from on-campus rates. Public universities in some countries charge modest fees; private and executive programs cost more. Ask for a full breakdown of tuition, platform fees, and any residency costs.
• Recognition and mobility: if you plan to work in a regulated profession or apply for a visa, confirm in advance that the specific degree is accepted where you intend to use it.
• Time commitment: expect 15–20 hours per week for a full-time online master's, or roughly half that for part-time study.

Online vs. on-campus: a quick comparison

A simple decision checklist

1. Is the program accredited and recognized in the country where you plan to use the degree?
2. Does the format (async, sync, hybrid) fit your schedule and time zone?
3. Are the language requirements realistic for you?
4. Can you meet the prerequisites and admission documents?
5. Does the total cost — tuition plus any residency travel — fit your budget?
6. Does the program offer the support you'll need to finish a thesis remotely?

If you can answer yes to all six, an online master's from a European institution is a credible route to the same degree title as campus study. If any answer is uncertain, resolve that point before you apply rather than after you enroll.

The message appears when the site detects a screen or device it considers too small or unsuitable for its layout, and it asks you to rotate your screen for the best experience. The practical fix is to rotate to landscape, widen the browser window, or switch to a larger device or a different browser. The available site information does not list which devices or browsers are officially supported, so if rotation and a browser switch don't help, check the site directly for current requirements.

What the message actually means

The notice is a layout guard, not an error in your account or a sign that the site is down. The page loads a notice that reads "your device is not supported! please rotate your screen for the best experience," followed by loading text while the site fetches its data. In other words, the site is telling you the current viewport is too narrow or the device type isn't one it renders well for, and it wants a wider, landscape-style view before showing the main experience.

This is common on sites with fixed-width layouts, game-style interfaces, or desktop-oriented navigation. The message is about display fit, not about whether you are allowed to use the site.

What to try, in order

1. Rotate your device to landscape. If you're on a phone or tablet, turn it sideways. This is the exact action the notice requests and resolves the message in most cases.
2. Widen the browser window. On a desktop or laptop, maximize the window or drag it wider. A narrow window can trigger the same notice even on a capable computer.
3. Try a different browser. If rotation doesn't clear it, open the site in another browser. Some browsers report device or viewport information differently, and a switch sometimes gets past the check.
4. Switch to a larger device. If you're on a small phone, open the site on a tablet, laptop, or desktop. The notice is most likely on small screens.
5. Check the site directly. The available information doesn't confirm which devices, browsers, or screen sizes are supported. If none of the above works, look for a support or contact link on the site itself for the current requirements.

What the message does not tell you

The notice does not say your account is blocked, that the site is paid, or that a specific browser is required. The available site information contains no pricing details and no list of supported devices, so don't read the message as a paywall or a ban. Treat it purely as a display-fit prompt until the site says otherwise.

When rotation won't be enough

If you've rotated, widened the window, and tried another browser and the notice persists, the limitation is likely on the site's side rather than yours. In that case:

• Use a desktop or laptop rather than a phone.
• Avoid embedded in-app browsers (for example, the browser inside a social or messaging app), which often report unusual viewport sizes; open the link in a standalone browser instead.
• Revisit later, since the site may adjust its device check.

Quick reference

The short version: the message is a layout prompt asking for a wider, landscape view. Rotate first, then widen or switch browsers, then move to a larger device. If it still appears, the site's own support channel is the right place to confirm current device requirements.

Mathplanet is described as a free, accessible platform for learning high school mathematics, with courses listed in Pre-algebra, Algebra 1, Algebra 2, and Geometry. That description comes from the site's own title and summary, so treat it as the stated purpose rather than a verified catalog: the page content captured at selenite.skysthelimit.dev does not display those courses, and instead shows unrelated game-portal material. Before relying on the site for study, open it directly and confirm the math lessons are actually reachable.

What the site says it provides

According to the site's own description, Mathplanet offers:

• Free access to mathematics learning material
• High school–level courses in four areas: Pre-algebra, Algebra 1, Algebra 2, and Geometry
• An accessible format, positioned as open to anyone who wants to study math

No pricing page, payment links, or subscription details appear in the available material. That absence is not proof the site is free in every respect — it simply means the captured page says nothing about cost. If cost matters to you, check the live site rather than assuming.

What the captured page actually shows

The page evidence conflicts with the math-platform description. The visible heading reads "your device is not supported!", followed by prompts to rotate the screen and wait for a game to load. The remaining text is a "welcome to selenite" interface with a theme selector, a "panic button," a "tab cloak" setting, and a fast-mode toggle, plus a generic education keyword block covering subjects from algebra to music and test prep from SAT to MCAT.

Two things follow from this:

1. The page is a portal or launcher, not a lesson page. The math content may sit behind it, or the domain may host something other than what the title claims.
2. The keyword block is not a course list. Terms like "MCAT prep" or "Calculus" appear as generic education vocabulary, not as confirmed offerings. Do not treat them as available courses.

How to check whether it fits your needs

If you want a free high school math resource, use this quick check before committing study time:

1. Load the site on a desktop browser. The captured page complains about device support and asks for screen rotation, so a phone may not render it properly.
2. Look for actual lesson pages. You want pages with explanations and exercises for Pre-algebra, Algebra 1, Algebra 2, or Geometry — not a landing screen with settings toggles.
3. Test one topic end to end. Pick a single concept, such as solving linear equations, and confirm you can read an explanation and attempt practice problems.
4. Check for account or payment prompts. If a sign-up wall appears, note what it asks for before entering any information.

Expected result: you should reach a math lesson within a couple of clicks. If you only find a game launcher, a theme selector, or generic education text, the site is not currently serving the math platform its title describes.

Common snags

• Mobile rendering: the page explicitly states your device may not be supported and asks you to rotate the screen, so start on a larger screen.
• Loading delay: the page says data fetching "should only take a second" — if it hangs, reload rather than assuming the site is down.
• Mismatch between title and content: the biggest risk here is trusting the description. Verify the lessons exist before planning a study schedule around them.
• Unverified scope: the four named courses are the only ones the description commits to. Anything broader you see in keyword lists is not confirmed.

Bottom line

Mathplanet presents itself as a free platform for high school math in Pre-algebra, Algebra 1, Algebra 2, and Geometry. The page captured at this domain, however, shows a game-style portal with unrelated interface elements, so the math offering should be confirmed on the live site before you depend on it. If the lessons load and are usable, it is a reasonable free option for high school math review; if they do not, look elsewhere.

Mathplanet describes itself as a free, accessible platform for learning mathematics, offering high school courses in Pre-algebra, Algebra 1, Algebra 2, and Geometry. The available information contains no pricing pages, payment links, or subscription signals, so there is no evidence of a paid tier. It also does not confirm whether an account or registration is required, so you should treat sign-up requirements as unverified until you check the site directly.

What the site says about cost

The site's own description is the clearest signal: it calls itself "a free, accessible platform for learning mathematics." That statement covers the core offering — high school math courses in four subject areas.

The provided page information includes no pricing keywords, no pricing links, and no payment platforms. That absence is consistent with a free resource, but it is not proof. A site can add paid features, ads, or gated content without those appearing in a short description.

What this means in practice

• Core courses: Presented as free. You can reasonably expect to read lessons and work through course material without paying.
• Anything beyond the description: Unconfirmed. If you encounter a prompt to pay, subscribe, or upgrade, that would be new information not reflected in the available evidence.
• Ads or third-party content: Not addressed either way.

Do you need an account?

The available information does not say. There is no mention of registration, login, student profiles, or progress tracking. That silence cuts both ways: it does not confirm an account is required, and it does not confirm you can use everything without one.

A practical way to find out in under a minute:

1. Open the Mathplanet site and pick a course, such as Algebra 1.
2. Click into a lesson or chapter.
3. Note whether the content displays immediately or whether you are redirected to a sign-up form.
4. If a form appears, check whether it asks only for an email or also for payment details — the latter would contradict the "free" description.

Expected result: If lessons open directly, no account is needed for reading. If a form blocks the lesson, registration is required at least for that part of the site.

Who the courses are for

The platform targets high school mathematics. The four named courses map to a typical progression:

If you are studying at that level, or reviewing it before a placement test or college course, the free course material is the part most likely to fit your needs. If you need calculus, statistics, or test-specific prep, the description does not list those, so check the site's subject menu before committing time.

Common sticking points

• Assuming "free" covers everything. The description supports free access to the math courses. It says nothing about tutoring, certificates, or downloadable materials, so do not plan around those.
• Assuming no account is needed. Equally unsupported. Test one lesson before structuring a study plan around anonymous access.
• Device or browser issues. Some educational sites load interactive elements that fail on older browsers or mobile views. If a lesson will not render, try a current desktop browser before concluding the content is gated.

Bottom line

Mathplanet presents itself as a free math-learning platform for high school courses, and nothing in the available information suggests a paywall. Whether you need an account is not confirmed — open a lesson and see whether it loads directly. That single check settles the question for your use case faster than any secondhand summary.
