There are several things you want to consider when you are looking for a review course. Firstly, think about how you will best learn. Do you like to watch videos, hear lectures, see simulations, or have access to discussion groups?
Secondly, think about your time commitment. Can you take time off from work for an in-person lecture, or are there even any courses near you? Or, do you prefer to have a self-paced course that you can access at any time?
