How to improve in VA?

Va is concerning,Quite literally.I am scoring around 156 in mocks ( 60-70% quants syllabus completed ) Distribution is 24~/46~/80~

I am practicing questions every single day,There are mistakes but i am not able to rectify them. 2-3 months before i was able to score 100~ in VA but the score has deteriorated and i am not able to progress. How do i move up from here given that i have 38 days left?
