i plan on taking prep class over the course of a semester, but do you think that would be sufficient time? I don't want to take it more than once... For example, should I take the prep class in the fall semester, and self study until the april exam? Or should I just take the spring prep course and take it in april? im not a very good test taker but i am pretty diligent. also, if i take it in the spring, i wouldn't be taking any classes bc i would have graduated, but possibly working in a lab. any suggestions?
