I was looking to solve more quant questions for practice. I know GMAT Quant is comparable to GRE Quant. Plus GregMat has it included in the two-month plan also.
So I was thinking of solving the 220 Quant Questions in the GMAT Official Guide 2018 along with the diagnostic test.
My main doubt is regarding its level. Is it harder or easier to the GRE level?
