I had to relearn calculus because I decided to study stats after finishing my BA in psychology. I was good at Math before but now I have to relearn it.. What did I do???? JUST LEARN IT AGAIN! I listened to lectures online; read the textbook.. I really don't think there is any shortcut to this. Also I am sure you didn't forget everything. You will surely learn faster the second time around.
