There's no bubble to burst as the GMAT is a comparative pool. When I took it there was the quant section and the verbal. I was 99th'ile for verbal and 90th'ile for quant. I was told the quant gets skewed as the majority of GMAT writers are actually engineers.Oh, as for degree of difficulty, I heard it's no longer CAT (computer adaptive testing). That shit is unnerving and the last several verbal questions took me most of my time due to the CAT function.
