I want to apply to higher level engineering schools like Berkeley, UC San Diego, and maybe even Stanford and Caltech.
At my high school, you must take AP Calculus AB before you can take BC. However, since so few people are actually to qualify to reach Calc BC as a senior (I took Algebra 2 as freshman, while most people took Algebra 1), they may get rid of the class entirely, meaning I would take AP Calculus AB as a junior, then possible another math class as a senior. Would it look bad to take AP Calc AB as a junior, then AP Stats as a senior? Would I be able to take the AP Calc AB class, but take the AP Calc BC exam? Should I take an Off-Campus period and take a Dual-Enrollment class?
I don´t know much about those schools, but let me tell you: your average applicant for those engineering programs has probably 750-800 math sat score, 700-800 math 2 sat score, both 5s on Calc AB and BC. Honestly I don´t know why you would take AP Stat over Calculus if you want to become and engineer. Also, I would suggest you to take AB and BC on the same year. I hope it helps! 
My son went to a smaller high school where he was only able to take calc AB (nothing higher was offered), and it did not hurt him in admissions. He is now at a v selective school studying engineering. However it was obvious that BC wasn’t offered as the math courses at his school ended with calc AB senior year. This didn’t hurt him in admissions, however most of the other kids in his program had taken BC in high school, so he did feel at a bit of a disadvantage once he got there. If you can easily take it at a local college, it may be worth your time. Otherwise, maybe your guidance counselor can make a note next year when you are applying to schools that it wasn’t offered senior year at your high school, so it doesn’t looking like you were slacking off.
Admissions officers do understand that kids from smaller schools just don’t have the same numbers of choices for AP classes as kids from bigger schools!
Agree with above post. I would just be a bit stronger in saying that if you do not take Calc BC I would ask your GC to specifically note in your recommendation that the course wasn’t offered during your senior year (unless perhaps it is very obvious from your HS prole). If dual enrollment class is do-able I’d strongly consider that.
It is very important that your counselor note if Calc BC is not available. Some schools turn in generic school profile writeups to colleges which don’t always get updated properly to reflect course offerings. We learned after applications had been submitted that the profile my son’s school provided to colleges listed three AP classes which had actually been cancelled that year.
Like your school, my son’s high school also offered Calc AB/BC as a two year sequence. This allowed them to cover a lot of material in depth during the BC year, much more than was needed just to get a 5 on the exam. I think it’s a good approach…assuming the classes are offered. It will help you to have that depth if you are going into engineering at a selective university, so try to take an equivalent course at a community college if you don’t get it in high school.
My D17 is a senior. She originally signed up for Calc BC (which can be taken without having Calc AB in her school), but then had a conflict in her schedule. She ended up taking Calc AB instead. Her GC noted on her transcript that the “lower level” class was taken to avoid a conflict and it was no problem. She was accepted into every engineering program to which she applied, plus honors college at each school.
One suggestion I can make is that you consider taking AB, study the three major concepts that aren’t covered by AB on your own, then take the AP test for BC. It’s been done before. Of course, that won’t help you figure out what math to take during your senior year but, again, your GC can note that you’d already gone as far as they offer.
Good luck!
@AlvaroSzi The problem that I have is that my school will no longer offer AP Calculus BC.
I would recommend you take calculus 2 through dual enrollment if that is at all feasible.
Colleges don’t penalize you for what your school doesn’t offer. But as stated before, you will want to at least know the BC concepts by the time you get there, regardless of how you accomplish that.
If you can only take AB as a junior because BC is not offered, consider taking calculus 2 (and perhaps calculus 3) at a local college as a senior, if you want to continue with math while in high school.
If BC is offered and you take it, consider taking calculus 3, linear algebra, and/or differential equations at a local college if you want to continue with math while in high school.
