there is a book called "the Statistics Problem Solver" for $4 (used) on amazon. Buy it! These problem-solver books are great for math & science classes. With thousands of solved problems and the steps for solving them shown, its like having a grad student tutor at your elbow.
You have to use the book correctly, though. The wrong way is to look at your homework problem, thumb thru the book until you see a similar one, then apply it blindly to your HW. A 5th grader could do that. Instead, use the book as a way to get practice until you understand the concepts. Go to the chapter matching your current classwork, cover up the answers and start working problems. If you get it wrong, read the correct steps, cover them up, do it again. Keep working problems until you get it. When you get midterms in class you'll almost be laughing because you know you can do them all.
Keep in mind that a standard expectation for a college class is 2-3 hours outside of the class for every hour in it. Your class will meet 3x a week for an hour, which means you ought to be putting in 6-9 hours outside of class for it. Do this, and use your time effectively, you'll do well in the class.
