Hi prepgmat95,
The actual Quant and Verbal Scaled Scores that you score on a CAT (including on the Official GMAT) are typically NOT integers (but those numbers are 'rounded off' for the sake of appearance). For example, with a V36, you may have actually scored any value between a V35.5 and V36.499 - and those types of variations in the Quant and Verbal Scaled Scores can sometimes vary your Overall Score by 10 points or so (relative to the Table Data that you might be referring to).
From what you wrote in your post, are you scheduled to take the Official GMAT sometime soon (re: in the next couple of days)? If that's the plan, then you should NOT try to do too much studying at this point (since we do NOT want you to 'burn out' before Test Day). In these last few days, you should limit your studies to general practice and light review (NO more CATs/mocks and NO 'cramming') - you would be better served by getting some extra rest so that you can go into Test Day calm, clear-headed and ready to work.
As far as what you could have done differently on this recent CAT to score higher - have you reviewed this CAT in detail? How many questions did you get wrong in each section because of a little mistake (meaning that you could - or should - have gotten the correct answer, but didn't)?
GMAT assassins aren't born, they're made,
