Next semester is my last before graduation. I couldn't fit PChem I in this semester, so had the teacher write me into PChem II for the Spring because first half isn't offered then (he didn't hesitate to write me in). I just need one PChem class to graduate and am worried that I might struggle because I haven't taken the first half. Will this affect my chances of doing well? Also, I will be taking CALC II concurrently with PCHEM, so I am very worried. Is this not a good idea? I really need to graduate next semester, due to personal things putting me in a tight position.
