In chemistry, you are given 10-20 problems over a chapter on a website called mastering chemistry. It is homework that’s usually due the day of the exam so you can have time to prepare for the exam and have time to ask the professor questions beforehand. This is also beneficial because it makes you go back to the lecture slides and you reread the information so you are learning it by yourself. It is a genius idea that makes you at least gets you to look at your material more than once.
