Did you have a bike when you were a child?
수험생
Yes, I had a vibe when I was a child. My parents bought it for me when I was 7 and I used to ride it around the neighborhood every afternoon with my friend. It was a red bicycle with a basket and it gave me a lot of freedom and confidence.

점수: 72.0제안: Pronunciation and minor word choice errors (e.g. 'vibe' instead of 'bike') and repeating unnecessary phrases reduce clarity. Improve by starting with a clear topic sentence, correcting key vocabulary, and keeping answers concise (max 3–4 sentences). Add one specific supporting detail using a linking word to make your response coherent. Also check verb forms and natural collocations (e.g., 'ride around the neighborhood', 'gave me confidence').
예시: Yes, I had a bike when I was a child. My parents bought it for me when I was seven, and I used to ride it around the neighborhood every afternoon with a friend. Because it had a basket, I could carry my books to my friend’s house, which made me feel independent and confident.
Do you think bikes are popular in your country?
점수: 60.0제안: Grammar, accuracy and fluency need work. Avoid filler words (uh) and use correct prepositions ('in my country'). Give a clear opinion sentence then support it with a specific reason or example using a linking word. Mentioning a brand is fine but present it clearly and explain why it is popular.
예시: Yes, I think bikes are quite popular in my country because many people use them for short trips and exercise. For example, the BNX brand is well-known for being affordable and durable, so many students and commuters choose it.
× Yes, I had a vibe when I was a child.
✓ Yes, I had a bike when I was a child.
The student wrote 'vibe' instead of 'bike', which is a lexical error that makes the sentence incorrect. This is a sentence structure/word choice problem rather than a pure grammar rule from the provided list; map it to 'Sentence structure errors' (ID 26). Suggestion: replace incorrect vocabulary with the intended noun. Proofread to ensure words match intended meaning.
× I used to ride it around the neighborhood every afternoon with my friend.
✓ I used to ride it around the neighborhood every afternoon with my friends.
If the student meant repeatedly riding with more than one friend, the plural 'friends' is required. If they meant one friend, the original is correct. Here the later sentence says 'with my friend' but earlier refers to 'a bike' singular; this sentence is acceptable if one friend; choose plural only if context indicates multiple people. Suggestion: confirm intended number and use singular/plural to match.
× Yeah, I think, uh, the bike is popular at my country, uh, and one of the bike, uh, popular is a BNX bicycle.
✓ Yeah, I think bikes are popular in my country, and one popular brand is BNX bicycles.
Multiple article and preposition errors: 'the bike is popular at my country' should be 'bikes are popular in my country' because we speak generally about a category (no article and plural) and use the preposition 'in' with 'country'. 'one of the bike popular is a BNX bicycle' is ungrammatical: use 'one popular brand is BNX' or 'one of the popular bikes is a BNX bicycle.' Also ensure noun forms agree: 'BNX bicycles' (plural) when speaking generally. Suggestion: use plural nouns without 'the' for general statements and use 'in' with countries; reorder phrase to 'one popular brand is...'.
