Dear Professor,
College is rough with course load and exams and projects. Without you, I don't know if I would keep my sanity.
Thank you for making this a little bit easier for me. Instead of just reading off of a powerpoint and talking with no emotion, you bring life to the class and allow me to understand the information.
Thank you for going above and beyond. The little props and application of the concepts to real life are more helpful than you realize.
Thank you for always being available. Even when I email you 4 times a day to ask 15 different questions, you are always patient in explaining everything to me.
Really great professors are hard to come by, but when you do, it's like a light at the end of the tunnel. Being a college student isn't easy, but neither is trying to teach 40 of them at a time. So you're awesome for doing it! You deserve a ton of gratitude for what you do.
Sincerely,
Your student
