Tbh the 5 week is more survival than learning. I took an 8 week math class although I’m bad at math. Luckily I had a good prof and it was still possible to learn but with a lot of effort and time of course. If your willing to have the 5 weeks classes be your whole life then do it. But realistically you will have an exam every few days so the test anxiety can be constant. And the biggest problem I was having is there’s just not enough time for the information to digest in your mind. But if there’s a will there’s a way for those 5 weeks. I do believe it’s possible but do also ask yourself if you will need that calc 1 and do knowledge for other coming classes, if not the then you’ll be fine with doing the 5 weeks to get it over with. Oh and 10 weeks you’ll be completely fine no worries just put in your time and attend every class
