Labs are a pain in the ass online, but easy marks. The quizzes that replace the midterm are extremely hard due to the time constraints, but if you understand what is happening conceptually then you can speed through it. Unfortunately, the course content is sometimes hard to understand and this is not a physics course where you can just plug and chug into formulas. If you have a good grasp of physics and enjoy it, then you may succeed. But if you are unable to grasp the concepts then this course may be your hardest for that semester (Fall 2nd Year Mech Engg). The content for this course also doesn't show up in later years to my knowledge so its not like you need to be good at this stuff anyways.
