Hi, I'm taking the SAT for the first time this Saturday and I'm not good at using desmos. Should I use up my two days to learn how to use it more well or should I just practice other stuff and leave it for later? The highest I've gotten on practice tests for the math is an 800 but it's probably not that accurate since some sets just have more questions I'm good at. I'm not expecting a high score so please give me a honest opinion!

I think I'm slow :((
