>>40369Not especially, it depends on how smart you are. Keep in mind that while a lot of the teachers might be educated, that doesn't necessarily make them good teachers or able to design tests and homework that make sure you know the material.
I coasted through a lot of university classes by just being really good at taking tests, not because I actually mastered the material. E.g. a multiple choice question might have something like "1", "-1", "16", "200". The answer is usually 1 in that case, because the two 1s tell you that it's likely the answer is 1. The 3 positive numbers tell you it's likely the answer is positive. So the only overlapping answer is 1. Most of the time this gets me the correct answer (even if the answers are in word form) even if I know nothing about the material. There were probably only 1-2 professors I couldn't do this with as they knew how to design tests. Half the time exams would usually have the answer to an earlier question in a later question.
Anyways, just keep in mind that ostensibly you're there to learn. Feel free to be lazy for non-core classes I guess, but if you're a physics major you should actually be trying to master the material instead of just being good at getting marks. It's very easy to get lazy about this.
