grammer問題

I have a friend who called Jacky. We are now studying in the same school. He is in class 2A and I knew him when I was in Primary 3. He is a sporty student and he likes playing a wide variety of sports, such as basketball, badminton, volleyball, etc. He is also very adventurous and smart. I hope our friendship will last forever.

use relative clauses more often in writing is good at all~
I think you may use much more connectives to link up the sentences
Besides,i have changed the last sentence for you~last means keep continue~

Overall,I think your english has much room for improvement~
The usage of grammer is quite good and you can try to use some difficult words^^

唔錯, 以下係我既修改

quite good.however,I think you can change"He is also studying in my school."
to be
"He is studying in my school."
