These are the two classes I am taking next year, and I would like to know the level of difficulty in them.
In Honors Chemistry, I have been getting straight A’s, except this semester which I am slacking off. Does AP Chem have similar concepts that Honors Chem does?
In Precalc I usually get an average of a B/C+ range. Is the curriculum in BC more difficult than Precalc?
I took AP Chemistry this year as well as Honors Chemistry last year. I had a terrible work ethic and got a B both semesters for Honors Chemistry. In my opinion, I believe that AP Chemistry was quite a large transition from the traditional Honors Chemistry class. Sure, it goes over the things that are reviewed in Honors, but not only does it go more into depth about these topics (for example, gases is a topic that was barely touched in Honors for me. In AP Chemistry, it’s a pretty major-ish topic), but also reveals new material such as acid-base equilibrium, solubility, etc. Seeing that you got an A in Honors Chemistry, I believe you’ll be fine for the class. It just requires a lot of time to be independently spent on it, whether it be through in-depth lab reports or simply homework assignments. I did slack in this class as well but managed to pull off B’s both semesters (I really need to work on my work ethic, lol).
As for Calc BC, I have a question. Have you taken Calc AB yet? Yes, Precalculus is completely different from Calc BC, especially when it comes to difficulty. However, I don’t believe this will be a problem if you have taken first-year calculus (Calc AB), especially since Calc BC mostly overviews Calc AB and a little bit of new material. You might struggle a bit more in the class, but, like I said before, having a first-year calculus background will help you out in Calc BC.
It really depends on the school, but if you do take BC, you will have to work very hard. BC requires a strong foundation in PreCalc, and the concepts are taught fairly quickly in order for students to be ready for the AP.
I strongly recommend AB, unless you studiously study and review your Precalc material.
Collegeboard recently revamped its AP Chem curriculum and test. Some concepts have been cut out from the new curriculum, but now it’s more about application, and less plug and chug. If you are getting A’s (not easy A’s) from Chem Honors, I wouldn’t be too worried, as long as you don’t slack off.
One thing I don’t understand, though, is the large discrepancy in your performance in precalc as to chem. Students don’t usually do well in Chem and get a C+ in precalc. Are our study habits and work ethics different for the two classes?
Honestly, I wouldn’t recommend AP Chem unless you’re really willing to put in the effort to completely understand everything. I took Honors Chem last year and breezed through it (straight A’s), so I thought I would be fine to take AP Chem. I was unfortunately very wrong. The class itself, at least at my school, wasn’t very difficult but it was very hard for me to learn the concepts throughout the year, and a lot of them I didn’t know at all. After taking the AP test on Monday, I can confidently say that I probably would have done just as well if I didn’t take AP Chem at all this year.
tl,dr: Take AP Chem if you like chemistry and are willing to put lots of effort in. If not, avoid it like the plague.
Personally I think those are the best and most legit ap out of all the ap. They offer a challenge and anyone who is actually good at the material, regardless of curriculum, do well On the test.
I know people who take calc test without class and get practically highest score in nation
FRom experience, chem is just chem knowledge. I took honors chem and the ap test was easy.
If u hate chem and math tho don’t do it. Cuz ap class won’t make u like them.
I meant precalc AB not BC 
I wouldn’t say my work ethic is different between the two, Chem just comes easier to me than precalc.
If you’ve taken Precalc, Calc AB shouldn’t be a problem for you. The only thing you should be aware of is that it is a rigorous course that moves quickly (although not as quick as BC) through material, and that you really need to have a firm foundation in precalc topics to do well.
