-read the booklet
-review your mistakes and almost mistakes (lucky gust questions)
These is the best method. The DMW has about 10 version. You are guaranteed to get at least 30-50% of same questions on your next test. So you complete review your old test, you know for sure you pasted at least half the questions. Also, reading the book is where the questions came from. They literally picked the questions off the booklet.
Other websites and 3rd party assistance will just confuse you. They have questions that they made up. Some of them don't even used the booklet. They are just teaching safe driving, not pass-freaking-test driving. Good luck
