From 670 (Q48, V34) to 730 (Q49, V40)

Dear all, I have just finished my 2nd attempt at GMAT and scored a respectable 730 (Q49, V40). My first attempt was in May and scored a low 670. I decided to re-take directly after the test but let some time pass (holidays, time to 'digest' the score). I think that the only differences between my 2 ...

Could you give the potential solutions?

Given my background, there is no point in doing a MBA unless it is in a TOP-3 school.

I think that those question can be very quickly solve with equation. At question 30 with timing pressure and stress from the test, having a standardised way of thinking about it can be easy. (anyway, that is just my opinion). I think the 'think in a clever way' approach is not that easy to apply in ...

I would approach is like this: You have X^2 everywhere, so you can just ignore it and focus on the Y part of the problem. You should just think that Y has a "good" (i.e. the final answer will be greater) effect when it is in the denominator and a "bad" effect when it is in the nu...

It is of course possible to modelise the whole thing but I think that number picking is much more efficient here. So let's assume Henry has 50 he gets 2 dollars for each dollar saved this year, then the solution is that he should spend 40 this year, save 10. Next year, he will have 20 which is 50% o...

We have 4 digits (7 minus 3 fixed) that can be potentially prime. Those digit can take the following values: 2, 3, 4, 5, 6, 7, 8, 9 Out of those digits, half are prime: 2, 3, 5, 7 To get to the result, we will use: Probability(At least 1 prime) = 1 - Probability(No Prime at all) We know: Probability...

Yes, that is my plan! Thanks for the support!
