To be honest, if you are scoring that with no studying on the mcat, I wouldn't even bother spending money on a course, let alone books.
Sit your butt down, go to Khan academy, and read through the synopsis things they have in each lesson (they are shortened versions of the videos). Do this for chem and bio. For P/S, google "reddit KA pysch word doc". That's all I used and got a 130 on P/S (i'm not a pysch major lol). Highlight only the main stuff (you'll know when you see it) and don't even read the rest after your first time reading through the ALL of it (only read what you highlighted over and over again).
Do AAMC practice stuff over and over and over. You'll get atleast a 500 doing that. That's plenty for pod school, including plenty for scholarships. Be warned though, I don't believe in the validity of practice exams (even aamc) too much. I got like a 493-501 on all my practice stuff and scored 85th percentile on my actual one 😱, YMMV.
You can still get into procedural fields as a DO if you want to go to DO school. Just don't mess around too much and try to be above average so you're competitive for those residencies. Your EC's are fine for either pod or DO so don't change that. Just shadow more / podiatry a little bit.
