The first thing you need to do is figure out what to focus on while studying. The most effective way to do this is to take a practice test, which can be found online through your state’s DMV website. Try to replicate the real test setting as much as possible—the time of day you’ll be taking it, a setting other than your comfy spot on the couch, and with a little noise happening around you.
Once you grade the practice test, you’ll have a clear picture of the areas that you need to study. Maybe you’ll see that you need to brush up on your traffic signs or tactics for severe weather condition driving, or maybe you need more information on special regulations for new drivers. Whatever questions you miss, know that these are the areas to focus on.
