Sample correspondence from happy students...
"Hi Susan! Well, I got a B on the test, my best score yet :) Thank you so much for taking time out of your weekend to help me."
"Hello! I just wanted to let you know, I got the high score on the exam!!! I don't know how many I actually got correct, due to the curve method, but I got 150/150! After the test, I felt like I had done pretty well....I just wanted to thank you. I've gotten A's on all three tests, and I know the practice exams definitely helped me."
"I did it! Just got my grades back. Got an A in Managerial Accounting! Thanks so much, Susan!"
