Oh gosh, okay nope. I haven't seen that kinda maths since highschool! I just had a quick google and not sure how much help I can be, especially at this time of night! I might have another look in the morning for you if you like cause I actually used to be pretty good with maths. I mean, it's not up there now but maybe if I look into it it might come back. In the meantime, do you know if your uni has access to Studiosity? It's a 24/7 online tool for uni students. I know you can submit assessments for proof reading and I'm almost certain they also offer free tutoring on there.. might be worth checking out? I've attached the link here for you in case you wanna give it a try and see.

There was also a really amazing free online maths tutoring program I used to use but I'm struggling to remember the name of it so will have a think and get back to you on that one!
I know Tuesday isn't far away though so am really feeling for you right now and wishing there was something I could do!!! 65% is a little on the brutal side!!!! I'm really not quite sure how best to help I'm sorry 😔
If there is something I can do, or if you just want to talk about how it's making you feel I'm here to listen and help as best as I can but I'm really sorry. I wish I could take some of the stress away from you. Do you think maybe the general exam anxiety is also getting to you? Like is there a chance you could pass but you're brain is making you focus on what you haven't done and therefore fooling you into thinking you're going to fail? Idk. I'm certainly hearing you and I know it's really not a pleasant place to be sitting in and I'm sorry you are.
