I currently have an F in a second semester class of my senior year

So, I’m 7 weeks away from graduation and I still have an F in Pre-Calculus. I’ve worked tirelessly with multiple tutors, done all my homework, and studied constantly for the past 2 months but I just can’t seem to pass the tests and they’re 80% of the final grade with no retakes. There are only 2 more tests and the final left so I could probably get a D but a C is unlikely. I just committed to CSU Sacramento, which was my safety school to begin with, and now I’m worried that they’ll rescind my admission. What should I do? Should I email the admissions office? If so, what should I say? Can my counselor do anything? I’m so panicked at this point, I really don’t want one regular math class to undo years of honors and AP classes.
