Jack Westin the MCAT CARS Tutor
The Jack Westin website has an entire backlog of Hundred's of daily CARS questions available for practice, as well as the option to sign up for their mailing list where you are emailed a new passage and set of questions everyday. This is a great way to remember to practice your critical analysis and reasoning skills everyday during your study period leading up to your MCAT test date. Each of the passages has the same layout as the official AAMC tests, which allows you to practice using the highlighting, flagging, and strikethrough functions.
Similar to the CARS question of the day, Jack Westin has recently started a science question of the day program where you can join a mailing list to get a free practice science question each day. Each day the question rotates through one of the three science sections of the MCAT.
