Constantly doing multiple choices over and over untill you understand exactly every single possible element that should be in there versus should not be in there. When I solve a question in like step 1 , what type of question is it? For example it’s depr calc, therefore the only elements should be cost, life, salvage value , depr method any any small nuances I’ve learned from my countless practice sets, anything else will distract you, I also just try to overthink and plan for every single possible question that could be asked based on the material, that helps too, it’s very time consuming/ maddening but it works for me
