<p>Alesteors: Taking the BC exam also gives you an AB subscore, so, for example, you may do poorly on the BC exam, but at least on the AB you could still do well. So from this perspective, I would say go for it. Also, I’m not sure how much you AP scores will matter after College admissions (in which case your exam is being taken too late to have an effect) so in this case I would also say go for it. On the side of workload and such, in my class (I arrived three weeks into the class, and was behind) we were REALLY behind by the end of the year, and didn’t get to do much series and sequences stuff, so I studied that myself (and ended with a 5). And since you’re taking AB anyways, if you have any problems, you could ask your teacher for help, as I’m sure he/she probably can help you. tl;dr: Go ahead, you do not have much to lose.</p>
<p>tonysdg: I have heard that engineering and mat related majors want you take their math courses at college, but for a major in like English they may accept your math credits (I may be wrong though - someone else should verify this). And your books are fine, newer editions are generally just error free and re-structured.</p>
