Hello Tim!

Your message made my day. It's nice to hear from you. Thanks for the compliment. You've been my student for a long time and I'm glad you are one. It's a pleasure of mine to teach you somehow. I just hope that you are learning .Anyway, just continue on improving although you are busy.  I desire that you will do well in your exam. You can do it !  Put a lot of effort into it :) And, you don't have to say "sorry" since being busy is a part of life. You just have to be good in time management. Perhaps, Learning is a life time process so I hope you won't get tired of it :) 

Anyway, I have some corrections for you below.
