Unfortunately, there are no drugs prescription or non-prescription that facilitate you remember what you study. The only article that can help you remember is not waiting until the final minute to study, studying properly, and getting good rest until that time the exam. One method I've used is the scent recognition method. Wear a distinctive cologne (or perfume or whatever) while you study and when you take the examination, spray that same cologne/perfume, etc. Sometimes that helps walk briskly your mind and helps you remember what you be studying. Otherwise, that's all you can really do.
