Kaplan Online Prep Classes for the New MCAT: Is it worth it?

Hello, I took my first MCAT in Jan and only scored 497 after self-studying with ExamKrackers textbooks and AAMC online materials. I especially need to improve CARS and Socio/Psych sections.
I'm thinking about signing up for the Kaplan online course and retaking the MCAT this coming fall or winter.

Is it worth $2300+ dollars?

Thank you for your time
