How to actually improve at the MAT? No seriously!!

I swear, this is not the same damn post reposted. I need legitimate help.
Im an international applicant, applying for CS. I've completed 13 past papers (rest I've set aside for mock test during the last week), but I don't really see any improvement in my MAT score. I am requiring up to 1 hour of extra time to complete my paper and I am still scoring in the 60-75 range.
I didn't see any improvement between 2007 to 2018 (but maybe that's because the papers also got harder?). I also do worse at the MCQs, and as luck will have it, its mostly MCQs now
I tried to do a few TMUA papers, but to be honest, I didn't find them particularly helpful. They seemed to be quite different from the MAT questions, which have a puzzle like approach to them? I found the same thing with the STEP Foundation module.
I also tried to do BMO1 problems, which turned out to be waaay harder than anything I've ever seen, and I couldn't do anything. I tried doing the Maclaurin and only am able to solve like 3 problems with a lot of extra time.
I tried the UKMT Senior Challenge, and got like a score of 95 in the 2023 paper, but I really only struggled with geometry there, and well, being a CS applicant, I don't think geometry has a huge effect on my MAT score (although, with the new format, perhaps that changes).
A lot of what I end up doing wrong is either missing/messing up a special case that I forgot about or I just end up staring at the question, not having a wild clue of how to solve it.
Legitimately, can you please offer advice? I'd also be extremely grateful if you can tell me how I should solve/study rather than just the resources/questions (although if you just have those, that'll also be hella helpful)

Here you go! Missed Session 2 which was on short MCQs, I'll watch that livestream at some point and see if they suggest any new techniques.

Hi,
Did you ever watch the second livestream and get those tips?

Hello maybe this thread will help: https://www.thestudentroom.co.uk/showthread.php?t=7432164#post99930283
I'm a UK student so I was able to go on a programme that gave us some good techniques for approaching problems. I'll check my notes when I get back home and post them here later.
Since they changed the distribution of questions I theorise the longer Qs will have one more maths based and one more logic based as one of the professor's who works on creating the paper said on a MAT Live Stream once that he felt applicants should be able to handle both since both are necessary in maths and computer science and their joint honours.
Side Note: with the new formatting, I dont know if it's the same for international students but all our working is on a booklet of laminated paper which we can't rub off and we enter our answers online so I suggest practice with a whiteboard closer to the time.
I hope this helps

That thread looks really useful, and I’d definitely be interested in seeing your notes when you get the chance—really appreciate the offer 🙌
Also, that bit about the professor mentioning the balance of logic and maths in the longer questions makes a lot of sense, especially for joint honours. And wow, laminated paper you can't rub off?? That’s such a weird setup—I hadn't heard of that before. Practicing on a whiteboard is a clever idea though, I’ll give that a go!
Thanks again—seriously helpful! 😊
