<p>Hi, I was doing a practice test for calc BC today and I started thinking. I know that the BC test gives you an AB subscore based on the questions that are taught in AB calc. I wonder if someone would sign up for the BC exam just to get the AB subscore. For example, you could just skip the questions relating to BC calc and use that time to do the AB questions. This would give you more time to work and figure out the questions that you are having trouble with. I asked my teacher about this and she basically thought I was stupid to even suggest it. I got a 3 on the AB exam last year, so this doesn't apply to me. Just a thought though...</p>
<p>Not all schools treat the subscore as being equal to the actual score.</p>
<p>In addition, not all students are adept at picking out whether it's a question that they should technically know how to do or not.</p>
<p>For instance, when you see an integral in the MC, how do you know whether it's one you should know how to do, or whether it's one that uses BC techniques? If you were that proficient in AB, you wouldn't need the extra time and probably wouldn't play that game in the first place.</p>
<p>Why on earth would you do that? If you only know the AB material, just take the AB exam.</p>
<p>MathProf is correct. Many schools do not count just the AB subscore without looking at the full BC score. What do you think the school will think if they see you got only a 1 (or at best 2, if you're lucky) on the full BC exam? They'll assume you took the BC exam because you felt you were qualified to take it, and the low score will certainly leave an unfavorable impression. Why risk that? You've gained nothing by trying to "game" the test. A 4 or 5 on the AB exam would be much more impressive.</p>
