<p>I am absolutely confused on how to calculate these scores.</p>
<p>For example, there are 45 questions on the section I of AP Calc AB.</p>
<p>Say I score 24 correct, skipped 17 and got 4 wrong, what is my raw score? (for only the multiple choice)</p>
<p>24 - 4/4 =23
So,
23 x 1.2 =27.6 pts.</p>
<p>wait what?? why did you 4/4?? where did 1.2 came from?</p>
<p>I just made that score up, but is 27.6pts good enough for a 5??</p>
<p>how do you calculate the subscore for Calc BC?</p>
<p>I don’t know how you calculate the subscore for Calc BC.</p>
<p>However, you should know that whatever you get an answer wrong, you lose 1/4 pt. That is why there is the 4/4. Omission is no point. Each correct answer is one point. </p>
<p>MC scores suppose to be 54 points. So, 54/45=1.2</p>
<p>Or in summary, here’s the curve for AB/BC:</p>
<p>MC correct - 1/4(MC wrong)]*1.2 = MC score; max 54
6 FR questions, each out of 9 = FR score; max 54</p>
<p>~70-108 = 5
~55-69 = 4
~40-54 = 3
~25-39 = 2
0-24 = 1</p>
<p>BC score for a 5 is approximately 65-67.</p>
<p>how do you calculate the frq score?? any penalties for wrong answers or do they just omit the score?</p>
<p>You have to remember that if you get a MC question wrong, you don’t lose just 1/4 of a point. You actually lose 1 point (out of the possible 45) for not having it right plus an addition 1/4 point for having it wrong.</p>
<p>I am pretty sure they omit the 1/4 mark</p>
<p>There’s no -1/4 in the FRQ.</p>
<p>There are six questions for the FRQ. Each question is 9 points.</p>
<p>Regarding your question about the BC subscore:</p>
<p>There is no BC subscore on the AB exam (but there is an AB subscore on the BC exam). This is because the BC test covers A, B, and C material. The total BC score is based on the whole test while the AB subscore is the score based on just AB material. It would be impossible to have a BC subscore on the AB exam because there is no C material on the AB exam.</p>
<p>Did that make sense?</p>

<p>That is what I meant, I want to know how to calculate the subscore for AB in BC</p>
<p>Oh, sorry. I would believe that the raw scores are calculated the same way; just that you need to omit the multiple choice questions that are C material and the 3 FRQs that are also C material. I don’t know if your practice test marks which questions are part of AB and which are part of BC. If it does, calculate your raw score just based on the AB questions. </p>
<p>As for the scaled scores, I would believe that you can use proportions to calculate your scaled AB score based on the overall BC scale (unless there’s a specific AB scale in the scoring key).</p>
