The last blog:

I don't like the end of the semester because it means I will have a lot of work and tests. About the blogs, I don't like them to end, I enjoyed it a lot because I feel that I met my classmates by reading their blogs.

Yes, I did help me to develop my English because I had to search several words to be able to express myself well. Also writing every week helped me to express myself better, build better sentences.

As I said before, one advantage can be that even though I didn't know almost anyone in the course before, I feel that by reading their blogs I got to know a part of them. It is a good way to interact with classmates.

At the moment I don't find any disadvantage, if I think of any I will leave it as a comment.

One suggestion would be to extend the deadline for 23:59.
