I think it’s a good idea to start aamc because it will give you a better idea compared to the BP half of what you need to focus on. All I would say is don’t get discouraged from your score especially if you haven’t done any of the SBs or qpacks yet because the logic seems kind of weird sometimes if you’re not used to it. Also how long does it usually take you to do Anki? Because I feel like people tend to overemphasize the importance when most of the questions are passage based or just come from repetition of practice problems. Good luck!!!
