This is super last minute seeming as I have a couple hours to make the decision, if I only want to pay $45, but would score preview be worth it. I take the test tomorrow and I took a practice test and scored 156, ... this is my first time taking the test so regardless I would want to retake it, but would it be better to keep my score, assuming I do get a 156. Or if I retake it and score better would it not matter. I thought i decided against buying it but i think too much lol, any advice is helpful
