Anxiety?: So what you're saying is the test info is stored in your brain, but you're having trouble getting it when it comes test time. I wonder if you're experiencing any test or performance anxiety? If you think it's a possibility, check out the link below. Many U.S. Universities have websites with great self help info.

Practice: You start by practicing over and over. Learning how you learn. Putting into practice and keeping good study habits. Habits is the keyword here. Making it a habit to both learn but to learn how to remember and recall what you learn.
