If you are paying for a class then you better learn stuff out off the class. Otherwise don't waist your money. Here is my suggestions for math.
Practice, practice, practice. Read your text book start to finish and do every single practice problem they give, find the answers on your own as much as possible and if you need to look up how to do them then write that problem down to do a day later after you have forgotten the exact solution. You should devote an hour or two a day to doing practice problems. This will help you develop an instinct for how to solve problems.
Now the second most important thing you need to do is learn how to reverse your work and check the answer. The beauty of math classes is you should always know if your answer is write or wrong. In undergrad there was never a single test that I left without knowing my exact score before it was graded. The reason was I worked all the problems forward and found the solution and then reversed the problem and worked backwards and came back to the right solution. Here is a very simple example if the problem is
4=X+1, then I can rearranging the equations to 4-1=X=3. This so now take X=3 and place it back in the original problem 4=3+1 that statement is still true.
By practicing you will develop the skills to find the solutions to your problems quickly and by reversing the equations at the end you will know if you have the right answer or not.
Good luck and if you get stumped on a particularly hard problem PM me and I can help you work through it.
