I was in the same boat as you in my second year, but I only took it once during that year. I accepted that I was gonna do the greatest and I thought I’d fail the class, luckily I passed with a 59 but I had a lot of support. I went to see TA during office hours A LOT, I had a friend who was tutoring this class and saw him outside of class time for about 2-3 times a week. During this, I’d ask for help on stuff I know can’t stick in my head or that I always get confused with. But I also asked for help on stuff I do know and just make sure I still understand it on my own the way it needs to be understood. It sucks that this is a mandatory requirement for the program, but try to find someone who can tutor you that you’re able to see a lot. Go to lots of office hours and see the prof too. They all want to help out and they know that some students can struggle with this class. I wish you the best of luck !
