Thank you very much for your help throughout my endeavors with calculus. You have allowed me to gain credit for a course that would have been merely impossible to achieve on my own. I can't be thankful enough for what your service has given me. I can assure you I will be in contact with you guys soon. Again, thank you very much and enjoy the rest of summer!
