For MATH 3A: personally, weisbart's class is a total joke. he extends hw deadlines if you complain, he gives you very little hw, he gives you final exams that only take an hour as opposed to the 3 hours allotted because of their extreme level of easiness, and his tests are the biggest joke of the century. basically, take him! during the final exam, you had to show all your steps in working out problems but he said "if you're running low on time, you dont have to calculate out the final answer" even though i finished the test 2 hours early and even TOOK A NAP! and then he curves super duper well meaning the average being like an A instead of a B or C. i dont know about other classes, but math 3a is really no effort at all and im so horrible at math. the only thing is to not count on learning from lectures because he talks about some random obscure topic like physics which has nothing to do with the hw or tests. so just make sure to understand the hw and practice tests and get extra help from the TA's instead and voila
