The teacher in this class is very nice and helpful. He sometimes joked and the atmosphere in the class was quite good.

Those were two simple sentences, usually you want to combine them to make it flow better.

By taking this class, however, I've really found that I have to work harder and harder.
For me(also maybe a number of Japanese people who take IELTS? haha), the most difficult part of IELTS is the writing section.
When we write sentences in another language, firstly we tend to think in mother tongue then translate the latter into the former in our brain.

*I didn't know what you were trying to get at, so that was my best shot at it. I assume you were trying to say something like: We think in our language first, and then write it in English.

I wish I could come up with words in English and not Japanese when I approach writing.

Good night.
