I haven't been doing much CARS practice since I got 130+ on AAMC FL 1 before studying, but lately I have been getting much lower scores on third party practice tests. On all official AAMC material (FL 1, FL2) I've gotten upwards of 90% of the questions correct, but on all third party material (Altius, Kaplan, NS) I've scored 127-128. Does anyone have any idea what could be causing this discrepancy and what I can expect on test day?
