Dear Riazul,
You will be very glad to hear that everyday we study in groups for half an hour after class hours and it help us a lot. When our teachers deliver their valuable speech, we may not realize the text completely. But we can solve these problems easily by discussing with one another in the group study. Please, join with us.

Thanks
Kamal
