Hey! I just finished with core curriculum and was wondering what prep tests I should be focusing on? It's about 16 weeks left of studying. I'm a full-time student so probably could take 1-2 prep tests a week.

when I take prep tests, should I be taking it as flex with 3 sections or with 4 because in the real test it will have the unscored 4th section? I know I'm only scored by 3 on the real so I don't want to inflate my score if the 4th preptest section helps me, but also want to build stamina by taking 4 sections
