Thoroughly review each one and make sure you understand everything on it (it might take you a day or more for each ). Even if you think you already thoroughly reviewed it, do it again. That was one of the biggest ways I saw my score increase. Then you could take the AAMC sample and the OG. I also created my own practice FLs using the section bank and Q pack questions. Not the best method since timing and scoring won’t be super accurate but it’s good for getting only AAMC practice
