Failed A-G required course in my first semester of senior year. Help!

I decided to take AP Gov this year because I love the subject and I may need the AP credits for my post-high school education career. Unfortunately, this year I was riddled with bad luck in my personal life. A minor car accident with a friend of mine led to a large argument, and I was kicked out of the group, and I had no one else to talk to during nutrition and lunch. This caused me to perform poorly in my classes because I honestly wasn’t feeling all too happy anymore. Then even more bad luck came by when I caught the flu, and I wasn’t in school on/off for about two weeks. This was about a month ago and right before our AP teacher gave us 4 consecutive mock exams for AP Gov. I missed out on a lot of reviews and I did extremely poor on all the tests as I had literally no time to study because I was making up absent work for other classes and I was also dealing with other tests I missed. This brought my grade down to a borderline D/C. Unfortunately, due to my absences, I pretty much missed a small unit that took place within that week. Our final and notebook check was today, I studied incredibly hard on my final, and I got a 90%! However, due to my absences, my notebook wasn’t complete, and this just kept my grade below a C. Now here is my issue, I am retaking the course next semester, however, I am extremely worried about my UC and CSU applications as this was my first failed class and it was an A-G required class. I am in my senior year and my first semester for AP gov ended today. I am extremely nervous that they would deny my application due to this fail, I am making it up next semester, but decisions are called out before the end of the second semester. I am retaking the course online; I don’t know if this information helps. Any tips? Will I be denied from the UC applications? Should I contact the UC schools I applied to?

Since you are retaking the course next semester, when you report the failed grade also note you are retaking the course.
If there are changes to your academic record…

Freshmen: If you change schools, add or drop a course, or fail to earn a C or better in a course after you submit your application, you must notify the UC Application Center by email or postal mail. Your correspondence must include your name, UC Application ID number and your signature (if you mail a letter), and will be available to all the campuses to which you applied.

If you receive an offer of admission, be sure to confirm with the campus admission office that they are aware of the deficient grade or schedule changes. Although you must notify the campus of these changes, we cannot guarantee that a campus can go back to review an application after correspondence has been received. Make sure to save a copy of your correspondence just in case.

So would it be best to send them an email now or when I start the course?

My advice is sooner rather than later but you could wait until you start the course since the UC’s will not have decisions posted until March. But you may want to find out if this will be an issue, even by retaking the course, so you have time to submit a few more college applications as a backup before February.

I’m aiming for community colleges around UCSD so I can get in via TAP. This is only if my admissions get declined due to this class and other classes this year (problems with my life really hurt my grades). I will contact the UC’s regarding this after my exams week just in case.

UCSD doesn’t do TAG anymore. The Transfer Admission Planner helps you with planning your coursework, but you can’t enter the school with it.

I know they don’t do TAG anymore. I thought TAP was their other thing, my teacher must have been confused when she told me.

UCLA and UCB have TAP. UCSD has neither TAG or TAP.
