I took the usual general physics classes about 4 years ago during my chemistry undergrad career. Now, I'm taking some more physics classes in order to go to grad school for physics. I'm going to be taking intermediate E&M and Mechanics. Will I have a hard time in these classes if I don't remember much from the general physics classes? I am reviewing some of the material, but I won't have time to finish it all before the classes start, and I'm worried that I will do poorly.
