Study Hint:
Find at least one or
two other students from the class with whom you can regularly do
homework and prepare for exams. Your classmates are perhaps the least
used and arguably your best resource. An efficient and effective study
group will streamline homework and study time and greatly improve your
written and spoken communication. The best time to use your classmates
as study/homework partners is after you have made an honest effort
on your own to solve the problems using your own wits, knowledge,
and experience. When you encounter an unsolvable problem, don't give up
too soon on it. Being stumped is an opportunity for mathematical growth
and insight, even if you never solve the problem on your own. If you
seek help prematurely, you will never know if you could have solved a
tough problem without outside assistance.
