GRE Prep
Though I didn’t need to give the GRE again, I used GregMat in early 2021.
I found it very useful, even thought it was cheap [$5 a month at the time]. See the old website here, This is what I used.
And if you are anything like me, you would start preparing for GRE just few months before you are planning to give it, so the one-month and two-month plan on GregMat were very useful. I needed to do very little quant for my GRE and Verbal resources here were just awesome.
What I liked the most was the fact that he had a systematic way for tackling all the different verbal problem type. Also the Vocab preparations were quite good as well. Overall my experience was good with this website.
