How Are the Korean Lessons Organized on HowtoStudyKorean?

HowtoStudyKorean organizes its lessons into numbered Units that run from learning to read Korean all the way to expert-level grammar. Each Unit contains 25 Lessons, 3 Quizzes, and a Unit Test, and the site states that its lessons will always be free. You can start at the Unit that matches your current level rather than working through everything in a fixed order.

The Unit structure

Every Unit follows the same internal format:

• 25 Lessons — each lesson includes 20–30 vocabulary words, grammar explanations tailored to that level, and audio recordings of every Korean word and sentence.
• 3 Quizzes — placed within the Unit to check your grasp of the material.
• 1 Unit Test — a cumulative check at the end of the Unit.

This repetition of lesson → quiz → test is what makes the Units self-contained: you can finish one Unit and know whether you are ready to move on.

The full list of Units

The progression is continuous: Unit 0 handles the writing system, and Units 1–9 move through grammar stages from basic to expert.

How to choose where to start

• Complete beginners should begin with Unit 0, since it covers reading Korean before any grammar.
• Learners who can already read Hangul can skip Unit 0 and start at Unit 1.
• False beginners and returning learners can sample the early lessons of a Unit and drop into the one whose grammar and vocabulary feel appropriately challenging.
• Advanced learners can jump directly to the higher Units (5–9) if the lower-level grammar is already familiar.

Because each Unit is built around its own vocabulary and grammar level, you do not have to complete every preceding Unit to use a later one — but the vocabulary in each lesson assumes the level of that Unit.

Supplementary material alongside the Units

Beyond the core Units, the site offers additional resources you can use to reinforce or customize your study:

• Workbooks for each lesson with exercises.
• A mobile app for quizzing yourself on vocabulary and sentences.
• Audio files for every word and sentence.
• Hanja Lessons explaining the root meanings of words.
• Short Stories for reading practice.
• Simple vocabulary lists and Vocabulary Lists showing how words are used.
• Anki Packages for digital flashcards.
• Conjugate buttons that show how verbs and adjectives are conjugated (completed through Lesson 75).
• Word Searches for word recognition practice.
• Paperback and Kindle versions of the lessons.
• Theme Lessons focused on specific subjects.

The Conjugate buttons appear on a separate purchase page, so treat that feature as a paid add-on rather than part of the free lesson content.

A practical way to use the structure

If you are unsure of your level, pick the Unit whose description matches your ability, open its first lesson, and check whether the vocabulary and grammar are mostly review or mostly new. If most of it is new, that Unit is a reasonable starting point. Then follow its 25 lessons, take the 3 quizzes as you go, and finish with the Unit Test before deciding whether to continue to the next Unit or repeat material.
