Hello everyone, I'm a high school student and wondering about the rigor of the AP Calculus classes that U.S. high school students often take. When I say rigor here, I'm talking about mathematical rigor as is commonly talked about with regard to math classes, and also whether or not the class is...

Hi guys, I really need help with deciding my courses for next year. Currently, I'm a sophomore in high school rising to a junior next year, and today, we began doing course selections for next year. Now, before I continue, I didn't just start thinking about my courses for next year today. I've...

Hello everyone, I am currently a sophomore in high school (year 10 by the US system), with two years before I graduate to university.

Hello, I was wondering if I should take the AP Calculus AB exam first or just take the AP Calculus BC exam. I am currently learning AP Calculus BC and my friends say that you have to take both in order to get college credit for both (I'm skeptical of this). Since AP Calculus BC covers the same...

I'm in need of the solutions/scoring guidelines to the AP Calculus AB Free Response Questions 1969-1978... I have the questions I just need the solutions/scoring guidelines only If anybody would like to share this document that would be wonderful it would really help me out in studying for this...

Homework Statement Do they even exist? I can't find them anywhere! I know they must exist... does anybody know where to find them... these are the scoring guidelines for the AP Calculus AB exam that they put out for the free response questions... I can't find any prior to 1998 and the...

To kick off my first post here I will begin with a desperate plea for help and guidance: My high school is unfortunately not one of the best by any means. It is gigantic and has over 3000 students in it, meaning that most of the focus is spent on teaching students who don't give a damn about...

I am a high school senior seriously interested in mathematics (and physics, and chemistry, but that's beside the point). I am wondering what would be the best path for me to learn involving mathematics now that the AP Calculus test is over (I don't want to have to wait until September to...

I am self-studying ap calculus bc. I need someone to recommand me a good prep book. I will also get a tutor. If possible also give me a link with good worksheets and solutions. please give me the link of the picture of the prep book you recommand I hear PR and Barron are pretty bad.

Homework Statement Let f be the function given by f(x)= (x-1)(x²-4)/ (x²-a). For What Positive Values of a is f continuous for all real numbers x? Homework Equations The Attempt at a Solution What I tried doing was separating the (x²-4) into (x+2)(x-2) then moving along from...

This is a bit different kind of help that I need compared to most other threads in this forum. I was not sure of where exactly to post this. But, since it is pretty much homework, and it's for my AP Calculus AB course, I thought this would be an appropriate place to put this thread. If not...

I'm taking the AP class on calculus AB, and I want to order a book. Anyone would recommend one? I think the Princeton Review is the best one, but the Kaplan's and Barron's seems good too, so any opinion would help. Also I'm taking AP macroeconomics. I know this is not a a topic that people...

does anyone know where i can find ap cal and/or phyics multiple choice sections of past tests?? i really need them to study. please help

Anybody taken the ap calculus ab exam? I'm taking the class right now, just curious to what you think about the exam. I expect it to be rather easy. ap calculus seems oversimplified. advice?

Here are some questions I have concerning AP Calculus that I have compiled while doing my homework assignments. Please help me answer them. Thank you very much! Questions: -Do you never need to worry about the chain rule when integrating? I'll add on to these questions when I have more.
