I feel for you OP. I had to retake calculus once in college.
You might find that youtube has some really good visual lectures that explain the concepts in ways better than your professors ever did. At least that was true for me.
The videos will certainly be faster than digging through notes and textbooks. And they combine visual and audio learning for people who don't learn as well from writing or reading.
Best of luck to you. And remember to relax, you will study and perform better if you do not concern yourself with results.
