The first, I really appreciate that you've spent time to read my writing task 1. I'd be very grateful, if you can leave a comment that shows:

• What are my good points? (Eg: main Idea, supporting details, vocabulary variety, ...)
• Where I need to improve? (Eg: introduction, conclusion, add more transition word, accuracy, ...)
• Which band do I get with this achievement? ( 5.5, 6.0, ... )
