I would take a test a day, making sure to go over your mistakes. Then, I would just study for a a week before your exam. I stayed up until 2 in the morning studying for the DAT the day I took it. I don't suggest that at all! Its best to refresh as it comes closer. Practice tests are good for stamina...in my case my fear of not peeing for 2 hours lol and make sure you use a white board, take breaks, and mimic real testing conditions. Good luck!
