<p>I’m going to say in terms of workload, Physics and Engineering are harder than Chemistry. In terms of “getting a good grade”, data shows Chem is harder. Chem classes are predominantly graded based on tests (usually ~90% of your grade is from exams) whereas Physics and Engs have time consuming problem sets in addition to labs like Chem, except the writeups tend to count for more and therefore take more time.</p>
