[Tuan Minh Pham]

Dear Dr. Lam,

My name is Pham Tuan Minh, my major is Electrical Engineering. I'm currently in need of your guidance, since I'm not smart, I need more exercises to further augment my skill. Please send me extra problems for me to practice, along with answer to check whether I'm right or wrong. Also, I will be most grateful if you can send me some extra material. This is my email: phamtua...@yahoo.com.

I'm looking forward to hearing from you,

Yours,

Tuan Minh.

PS: You are a good lecturer, however, I'm not so good and my midterm exam is horrible, but it's not your fault so don't feel sad when you mark it. I'll try my best. Thank you for your guidance.
