Follow these steps. Each one tells you what you should see.
- Read the question and say any Korean text aloud once. You should see four choices.
- Pick one choice by click, tap or by pressing 1, 2, 3 or 4. The Check button turns active.
- Select Check. You see "Correct" or "Not quite", the right answer and a one-sentence reason. Select Next.
- After question 15, read the summary. It shows how many answers were correct in this session and links to the lesson and deck for the questions you missed.
Question order and choice order change every session, so a retake is never the same sequence. If you get stuck, sketch the block grid on paper: initial top left, vowel beside or below it, final at the bottom.
What Does the Korean Syllable Blocks Quiz Cover?
The quiz has 15 questions about how blocks are built. The questions ask you to name the three positions, to build and choose blocks, to tell vertical, horizontal and mixed vowels apart, and to handle reading order and double finals.
| Position | Korean term | Always present? | Example in 곰 |
|---|---|---|---|
| Initial consonant | 초성 (choseong) | yes, ㅇ if silent | ㄱ |
| Vowel | 중성 (jungseong) | yes | ㅗ |
| Final consonant | 종성 (jongseong), also 받침 (batchim) | no | ㅁ |
The lesson behind this quiz is Korean syllable blocks. If a question about the final position surprises you, read final consonants (batchim) in blocks first.
How Is the Korean Syllable Blocks Quiz Scored?
The quiz gives one point for each of the 15 questions you answer correctly on the first try in the current session. At the end it shows a line such as "You answered 12 of 15 correctly in this session", and the same wording appears in the page data. There is no timer, no streak and no ranking, so you can slow down and say each answer aloud.
The count is not a CEFR level, a TOPIK level or a measure of fluency. It only shows what you recalled today. Your answers and score stay in your browser and disappear when you close the tab, unless you choose to save progress on your own device. Questions that name the three positions use the standard Korean terms with English glosses, and the reason always repeats the gloss.
What Should You Know about Syllable Blocks First?
A syllable block is one square unit of Hangul that holds one syllable. It has an initial consonant, a vowel and, in some blocks, a final consonant. Korean writes these letters in a fixed pattern, so a reader finds the same three slots every time.
How Do Vowels Change the Layout?
The vowel decides where the other letters go. Vertical vowels ㅏ ㅐ ㅑ ㅒ ㅓ ㅔ ㅕ ㅖ ㅣ stand to the right of the initial. Horizontal vowels ㅗ ㅛ ㅜ ㅠ ㅡ sit under it. Mixed vowels ㅘ ㅙ ㅚ ㅝ ㅞ ㅟ ㅢ wrap around the initial, with one part under it and the other beside it.
| Block | Pattern | Letters | Sound |
|---|---|---|---|
| 가 | initial + vertical vowel | ㄱ + ㅏ | ga |
| 고 | initial + horizontal vowel | ㄱ + ㅗ | go |
| 감 | initial + vertical vowel + final | ㄱ + ㅏ + ㅁ | gam |
| 곰 | initial + horizontal vowel + final | ㄱ + ㅗ + ㅁ | gom |
| 과 | initial + mixed vowel | ㄱ + ㅗ + ㅏ | gwa |
How Are Blocks Stored in Computers?
Unicode (the text standard behind every Hangul font) composes blocks with one formula: 0xAC00 + (initial index x 21 + vowel index) x 28 + final index. There are 19 initials, 21 vowels and 28 finals, counting "no final" as one, so 19 x 21 x 28 = 11,172 possible blocks. For example 한 is ㅎ (index 18), ㅏ (index 0) and ㄴ (index 4), which gives 0xD55C. You do not need the formula to read Hangul, but it explains why every block is regular.
What about Double Finals?
Some blocks hold two consonant letters in the final position, such as 닭 (chicken). They still count as one position, the final. In 닭 the final is pronounced as one sound, so the block reads dak. The batchim quiz covers the pronunciation.
Sample Questions with Answers
These six questions come from the quiz, with the answer and the reason for each. They also work as a no-JavaScript preview. The sixth sample turns on position, not on sound: the question asks where ㅁ sits.
Sample Question 1 and Its Answer
Question: Which letters build the block 한?
Choices: ㅎ + ㅏ + ㅇ; ㅎ + ㅏ + ㄴ; ㅏ + ㅎ + ㄴ; ㄴ + ㅏ + ㅎ.
Answer: ㅎ + ㅏ + ㄴ. Why: The block is initial + vowel + final: ㅎ, ㅏ, ㄴ.
Sample Question 2 and Its Answer
Question: Which block uses a horizontal vowel?
Choices: 고; 가; 거; 기.
Answer: 고. Why: ㅗ sits below the consonant; ㅏ, ㅓ and ㅣ stand beside it.
Sample Question 3 and Its Answer
Question: How do you write the syllable "o" as one block?
Choices: ㅗ; ㅇㅗ; 어; 오.
Answer: 오. Why: A silent ㅇ holds the first position and ㅗ goes under it.
Sample Question 4 and Its Answer
Question: What is the first position of a block called?
Choices: Vowel (jungseong); Final consonant (jongseong); Initial consonant (choseong); Placeholder (batchim).
Answer: Initial consonant (choseong). Why: Choseong, jungseong and jongseong are the three positions, in that order.
Sample Question 5 and Its Answer
Question: How many positions can a block have at most?
Choices: 2; 3 (initial, vowel, final); 4; 5.
Answer: 3 (initial, vowel, final). Why: Even double finals, such as the ㄺ in 닭, fill one position.
Sample Question 6 and Its Answer
Question: In 곰, which position does ㅁ fill?
Choices: The final; The initial; The vowel; None.
Answer: The final. Why: 곰 is ㄱ + ㅗ + ㅁ, and ㅁ sits at the bottom as the final.
Tips before You Start
- Draw the block grid on paper for the first few questions: initial, vowel, final.
- Say each block aloud as you decide; sound and position help each other.
- Use the syllable builder tool for any block you miss, because it shows the parts live.
- Look at the vowel first; it tells you the layout.
Which Mistakes Does the Korean Syllable Blocks Quiz Catch?
The same few block errors appear again and again.
- Putting the vowel before the consonant, as in ㅏㄱ for 가.
- Writing ㅇ at the end of a block when the syllable only has a vowel start.
- Mixing vertical and horizontal vowel positions, for example placing ㅗ beside the consonant.
- Counting a double final as two positions instead of one.
What Should You Study after the Quiz?
Build blocks live in the Hangul syllable builder and drill common blocks with the Korean syllable flashcards. Review Korean syllable blocks for any missed layout. The next quiz in the sequence puts blocks to work in the Hangul reading quiz. The Hangul quiz collection lists every other check.

What Does This Quiz Not Do?
The quiz does not test final-consonant pronunciation or sound changes between blocks, which belong to the batchim quiz. It does not ask you to handwrite blocks, and it treats Unicode as background rather than as a test topic. All Korean text in the questions and answers was generated and is waiting for review by a Korean reviewer.
Frequently Asked Questions
Are the blocks tested with audio?
Some questions include an optional replay button for a block such as 물, but most questions test position and shape, which do not need sound. Audio never plays by itself. Clips are generated and were approved by Min-ji Park on 15 October 2026. If a clip is unavailable, the button is hidden.
Does the quiz include double finals?
Only one question does, with 닭 as the example. The point is that two letters in the final slot still count as one position. Pronunciation of double finals is a sound-change topic and is covered in the batchim lessons and quiz.
How is this different from the syllable deck?
The flashcard deck trains fast recall of common blocks, and it schedules repeats over days. This quiz tests understanding of how blocks are built and gives a reason for each answer. Use the quiz to find gaps and the deck to fix them.
Where do I learn the block shapes?
Start with the Korean syllable blocks lesson, which shows the five block patterns with examples. The syllable builder tool lets you assemble blocks yourself and see the result. Both are linked from the next-steps section of this page, and both include examples with sound so you can check your reading.
Is the quiz free?
Yes. The quiz is free, needs no account and runs in your browser on a phone, tablet or computer. Nothing you answer is uploaded to a server. If you choose to save progress, it is stored on your own device only, and you can delete it in the settings at any time.
