tests or assignments

Personally i rather have assignments to due then to study for a test. I do not like that a class recieves its grade on 3 tests. What if you arent the best test taker? that is not fair to those students. Assignments make a student learn and also tests them on there knowledge of the class. It might be a little more work but that is why each class has TAs. to help out the teacher with the grading.
