It is a pleasure to have you in my class. You do fine during class. It is very important to participate in class. The more you speak the better your speaking skills be become.
About your homework assignments: they are very important for improving your writing skills and they inform me where you need help to improve your writing skills. I can not help you improve your writing skills you don't write! In your email you write that you have met new friends. That's very good. You also write " I was happy to learn of this" What do you mean "this?" Do you want to learn to speak and write English?
Please finish your workbook pages and then give them back to me. If you have questions please ask me. I gladly answer all your questions. This my job the answer students' questions. I am waiting for you before class and after class. You also can write your question via e-mail.
I wish you the very best
