Should I hone on Chem/Phys or try to perfect the other sections?

I'm scoring around a 500 right now, and my weakest section is Chem/Phys. I struggled with orgo in class, and struggle on the MCAT. the content knowledge can be confusing. However, I'm getting around a 125-126. While I'm quite low in the other sections, in terms of confidence to improve, here is my ranking: 1. Bio/Biochem 2. Psych/Soc 3. CARS If I plan on taking the exam in the next 3.5 months, would it be better to perfect these three sections instead of labor away at Chem/Phys?
