Hey guys this semester I got a D+ in AP Calc AB (11th grade). Other than this one subject all my other grades are pretty good. IDK what happened in math, but I plan on retaking it in the spring and that will replace the “D” (and GPA). However colleges will still see that I got a D+ in math. My SAT score is 1550. So I was wondering am I totally screwed or do I still have a chance at schools like UC Davis, UC Santa Barbara, or UCSD. I think my UC GPA will be around a 4.0 weighted (uncapped). Going to apply undeclared. I am taking a rigorous course load and have gotten all a’s and b’s in the others (8 total AP /weighted classes in 10th and 11th grade).
Take my advice with a grain of salt (just another high school student only a grade above you), but I don’t think it would be TOO big of a deal for those colleges if you manage to bring it up to, I dunno, a B or, more realistically, a C. As long as you can keep your GPA in a good range, I’d still give you a good chance. Besides, those schools’ acceptance rates aren’t too rough.
You say your 4.0 is weighted + uncapped? I’d definitely try to bring it up for a weighted GPA. Out of curiosity, what’s your unweighted? Your SAT is really good (assuming you’re using the new SAT scoring), so it could maybe make up for your GPA drop to a good extent.
Hope you do better, and there are a lot of good free Calc sources online if you are struggling. Don’t stress out about your D too much, but try to bring it up next semester and try to keep your grades as high as possible through 11th grade. Good luck.
I don’t know what my unweighted is but I don’t think its that great. Thanks.
In that case, see if you can’t make next semester something of a last-minute clean-up. That seems to be your biggest issue at the moment, and I feel like your chances with a somewhat selective public school like those above would be really good if you could just improve it. Ask your counselor about it, too.
I feel like as long you make up the class and explain to them why you struggled in Calc in the academic explanation sections on the app they will be able to overlook the D+ considering the rest of your grades are good. 
Telling admissions why calculus was hard, is making them think. How would this student do in college courses
