Retake pre calc

So… I took pre calc last year and my teacher liked to grade things all-or-nothing. Even with A’s and B’s on the tests I ended up with a C first semester and D- second semester.

I was planning on retaking it over the summer but I had family pass away and had stuff to help with. Right now it’s on my schedule but it feels like a waste of my time as I understand the concepts plus I have the same teacher and I’m afraid I will get zeros on my notebook that we turn in 4x/semester if I do one thing wrong in it. Last year, I got the points 2/8 times and the teacher wouldn’t tell me why or what I did wrong.

Should I talk to counselor and see if I can take it some other way? Or what?

If you feel confident in your skills and you can take some sort of test to prove that you’re competent in Precalc, I don’t see why not.
