How do i stop making silly mistakes in A level Maths papers?

Every time I sit a past paper, i always lose up to 15 marks on sily mistakes. things like randomly forgetting a minus or typing in the wrong number to the calculator. Its weird because i find the questions easy but can just never stop making these mistakes.

Does any1 have any advice on how i can stop doing this? im afraid it could end up being the reason i don't get an A*

Ok so this also happens to me but I’ve worked on it because as the material gets harder I can’t afford silly mistakes. So what I do is:
-targeted practice of topics by identifying where I often make mistakes


-show more working honestly I treat the difficult questions a bit like proofs because by writing it all out mistakes are less frequent (for instance, mechanics questions that involve y2 trig)





-focus as much as you can during practice papers , treat it as a real exam


So to be more specific say I often make stupid mistakes with substituting 1+tan^2(x)=sec^2(x) by putting cot instead of tan, I write out how the identity is derived, takes like 20 seconds. If it’s a common mistake it’s worth it. In general I show a ridiculous amount of working in exams -I’ve been told that some non proof answers are like proofs but for me, this helps reduce mistakes .

You have to be methodical and careful and for me personally , I’m willing to sacrifice time to review questions to go through the exam carefully. It pays off because when do I understand the question better, whilst doing it or an hour later after I finished an exam slight early?

it helps if you clearly set out your working like a step by step like one line per step and also if you have time check all your working at the end. and if you're making silly error like 1+3=5 literally put simple things like this in your calculator it can save you so many marks
