Hi,
My sincere advise would be to give an official mocks- as they are closest to the real exam.
I got a 555 on my actual exam and was getting 10-20% lower scores in my
magoosh mocks.
The mistake that I made was to rationalise the low scores and blame it on the situation/ nerves/ lack of sleep, etc. rather than focusing on what I was doing wrong.
Having said that, my advise would be to focus on quant and DI- as they currently look like your weak areas.
V-81/82 is a decent score
Q- you should target close to 88
DI- target should be above 80
Quant and DI scores indicate that you may be struggling in solving 700+ (hard questions) either conceptually or you are not able to manage time. Please have a detailed look at the error logs of your mocks- that will give you best direction
