Homework? Tests? Not really. Final year Bachelor's Law school student here. No tests, no assignments other than for the odd practicum. Nothing but 1 exam for each class that makes up 100% of your grade and the occasional paper that has to be written (currently working on an unfinished one on nemo tenetur and cryptography law, 46 pages as of now). But it obviously depends on what you're studying and where. Some countries and universities have way higher standards than others.
