This is all the questions that I have for the remainder of the semester. I really appreciate your help and I am glad you are available for students like me. I've been trying to do this own my own for 10 weeks but the problems just got too hard for me and I've not been making the grade. Please let me know if I can do anything for any of you tutors, I will. Thanks again. We really appreciate your brains! You are impressive! All of you!
