Saw in one of your previous posts that you are planning on taking the DAT in January. I would just study your butt off for that test. Do a ton of practice questions from DAT Destroyer and Bootcamp, take a lot of full-length practice tests to develop your stamina, and give yourself the opportunity to take it again if you don't get a high score.
I also saw that your goal is a 20. Test averages are going up every year (see table below; especially for enrollees which is 2nd half of table) and I don't think 20 is as competitive as it used to be.
