Get a program that has practice tests. Take 100 practice tests.
I used Gleim like this. Others use Sheppard Air.
What I did with Gleim was read the E-book that covers the material. After each practice test, they have "study guides" which take those missed questions, re-ask them, and then give you the correct answer and explanation (along with why the others aren't correct).
Do that enough times, and you'll make a high score. I made a 98 a few days ago.
If you just want to memorize the questions in a few days, do Sheppard Air.
