<p>Say that you got part a wrong on an FRQ and continued to use the information derived from part a in all subsequent parts of a question. If your methods are correct, will you still gain full credit for those subsequent questions, even if your actual answers are wrong because you're using incorrect values from part a? </p>
<p>So...what I'm stressing about is calculus BC. I am pretty sure I did everything right on question 6, but if my part a is wrong...all that follows will be off as well if I am plugging in a faulty series. >__< (I know part a should have been easy; I over-thought. Stupid.)</p>
<p>Yes. As long as you use the incorrect answer correctly in subsequent parts you get full credit.</p>
<p>Both my AP physics and AP calculus teachers said, if you methods are correct, you will still gain full credit for those subsequent questions even if you part A is incorrect. Don’t stress about it.</p>
<p>I think if you answer a comparison question wrong based on previous calculations, you’re ineligible for points. So, for example (this obviously isn’t calculus): which has the higher mean, A or B? If B actually has the higher mean; but you calculated A wrong, making you think it has the higher mean, you wouldn’t get any points.</p>
<p>let me get this clear.</p>
<p>Like for part a you took the antiderivative of k’(x) to find the blah blah blah. and that was wrong and for the rest of the parts you worked with that same formula and your answers were wrong, but you were doing all the steps correctly.</p>
<p>If this describes you, here is what I know for a fact.</p>
<p>If EVERYTHING in part a is wrong, you get NO credit, but if you get partial right like integrand, limits, answer, they always give you partial credit. BUT, if you used that wrong answer for the rest you will most likely be doing EVERYTHING wrong for parts b,c, and possibly d. Because of your early mistake you will receive ZERO credit for those, unless the specific requirement and point system they have matches the work of yours. Like you randomly put 0 1 as the lower and upper limits, and that was the answer you will get points.</p>
<p>So, all in all, your work has to match there rubric guideline. No credit for following incorrect work. (Sorry if it seems harsh, but it’s the truth and it’s always good to know that then false truthfulness. I witnessed this today on my final FRQ question #2.</p>
<p>It really depends on the nature of your error. If the work you are doing approximately matches the difficulty level of the actual work required, you are oftentimes eligible for credit on later parts for doing the right work with the wrong function.</p>
<p>If the work you’re doing doesn’t really match the difficulty level of the actual prompt as it should have been, then a lot of times you’re out of luck as Indianjatt described.</p>
