Is it doable to take a calculus-based Physics class without ever having taken Calculus? I am currently registered in the class and it has been a week and half. Some of the stuff is completely new to me and I want to see if others have done the same. I need to take General Physics I & II for Physical Therapy school and that is why I got the teacher to bypass the pre-req of Calculus. I have only taken Pre-Calculus and that was 2 years ago.
