How your answer gets corrected

This is the real interface, not a mockup — the same block you get after a mock test. Example taken from a real graded answer.

You said

I am a morning person because I always get up early and I feel productive in the morning.

Use this today

I'm definitely a morning person because I always get up early and feel really productive during the morning hours.

Aim for this

I'd say I'm a morning person through and through — getting up early gives me a real productivity boost that lasts the whole morning.

thêm 'through and through' — nhấn mạnh tự nhiên hơn
'productivity boost' thay 'feel productive' — collocation mạnh hơn

Where your pronunciation slipped, and how to say it

However, I had to choose one, I would go with my time management skill.

Say it like this

however — nghe gần như mất âm, chỉ còn vài âm rời rạc→however — /haʊˈevər/, bật rõ /h/ ở đầu và giữ nguyên âm đôi /aʊ/

skill — nghe thành 'SKUs', mất âm cuối /l/→skill — /skɪl/, kết thúc bằng cách đặt lưỡi chạm vòm miệng trên rồi mới thả hơi

The original sentence is kept verbatim, errors included. Pronunciation is measured at phoneme level, so it names the exact word that slipped.
