I took the GMAT and didn't meet expectations on on the quant section. I'd really appreciate some suggestions for which study materials people found to be the best. I've recently worked the OG and formerly Kaplan. Looking for something a bit more challenging than the OG, but still structured as close as possible to the actual GMAT. Please provide suggestions. And, specifically, I've heard mixed reviews about purchasing
GMAT club tests and Jeff Sackman's GMAT Hacks. Please respond if you have any info.
Thanks so much!
