AP Calculus BC — is a 5 realistic from a practice score of 3 with 6 weeks to go?

I've been scoring consistently at a 3 on AP Calculus BC practice exams, averaging around 58–62% on multiple choice and falling apart on the series convergence and parametric sections of the FRQ. I have 6 weeks until the exam and I'm trying to figure out if a 5 is actually reachable or if I should recalibrate and focus on locking in a 4 instead.

I'm spending about 1.5 hours a day on calc right now, but I also have AP Physics C and AP Language at the same time, so I can't go all in. My teacher says my conceptual understanding is solid but that I'm losing points to algebraic manipulation errors and not providing enough written justification on the FRQ. That's a different kind of problem than not knowing the material.

Series is where I feel the most lost — ratio test and geometric series I can handle, but the alternating series error bound and Taylor/Maclaurin polynomial questions fall apart in the details. Has anyone made a similar jump in 6 weeks, and what would you prioritize?

The FRQ justification issue is a real score killer because they award method points explicitly on the rubric. Take 3 or 4 released FRQs from College Board archives, write your justifications, then compare them word by word to the scoring guidelines. You'll see the language patterns quickly and start writing them automatically.

Going from a 3 to a 5 in 6 weeks is hard but not unrealistic if your conceptual foundation is solid and the issues are execution. Algebraic errors and FRQ justification are fixable — they're habits, not gaps. Slow down on problems you know and write out every step until it's automatic.

For Taylor series, don't try to rederive everything — memorize the 5 standard series cold (e^x, sin x, cos x, 1/(1−x), ln(1+x)) and practice manipulating them. The exam questions are mostly substitution and composition, not derivation from scratch. That alone should fix most of your series losses.

Realistic framing: if you fix the algebraic errors and FRQ justification, you're probably already closer to a 4 than your practice scores show. Whether you hit a 5 depends on how much series you can lock down in 6 weeks. Aim for a strong 4 as your floor and treat the 5 as a stretch — that framing keeps you from burning out the last two weeks.
