Being that the homework is worth roughly ten percent of your grade, it might be quite a risk both for issues of academic dishonesty and for issues of learning PChem to rely too heavily on group efforts. Of course, and I don't want to discourage it. The grade guideline given above are upper bounds. If your grade exceeds the value given, e.g., if it exceeds 360 then an A grade is guaranteed. One can simplify one's life at the outset of PChem if you were to purchase and to understand how to use Maple.
Maple is a program which performs symbolic, numeric and graphical functions.
It takes derivatives, plots in two or three dimensions, takes limits and in general simplifies the tedious aspects of mathematics. I will use it when I do the PChem assignments. Somethings Maple can not do. It can not think. Maple will not be available for your use on examinations but hopefully the math on exams will not require it.
