About writing section

Hi. I’m new in this site and i have a question. in every lesson has a writing part. what do i have to this part. in this section what i suppose to write.

@toprak - You can write about whatever you like. You can write about the lesson, you can answer one of the topics available when you click the topics button or you can write some sentences using your new vocabulary. It is entirely up to you. Writing is not mandatory but when you reach a certain level it is a very effective way to start using your active vocabulary. Good luck!

Thank you for answer, Mark. I think my english level is lower-intermediate and my writing more lower. I can’t make english sentence easıly. I want to improve my english and i guess writing is more important for doing this. I will try do on my best.
