so I'm 3 weeks away from taking the mcat and I have taken 5 TPR tests but can't seem to increase my score no matter how hard I try!!! I've been studying for 3 months, and I revoew the concepts I get wrong but for some reason I can't get increase from my persistent score of 24. I'm very stressed out bc the mcat is near, and it seems like my hard work isn't paying off. Advice??
