I’m a pre-data science major, and my current classes for next quarter are CMPSC 9, MATH 4a, and PSTAT 10? I’m a little stressed out because I a lot of people have said these classes are hard, and I know my ass isn’t smart enough to get good grades for all these classes. The thing is that I failed MATH 3b my 2nd quarter of freshmen year, so I wasn’t able to take any of these classes my 3rd quarter. Should I drop a class? Maybe drop CMPSC 9 because that’s the last CS course I have to take? If I do drop one of these classes, will I be behind?

Random question, but do I have to complete all my GE classes by a certain time, or does it have to be done by my 4th year? I'm not behind on it or anything, just curious.
