Currently, I memorized 15 Sets of GregMat vocab lists. Even though I find the vocab in the current GRE TC/SE question familiar and doable, most of the vocabulary in Bigbook seems unfamiliar to me. When I searched Bigbook vocab in the entire GregMat list, I couldn’t find most of them. However, when I looked at the meaning of those words and tried to utilize Greg strategy, I can solve most of them.
I am afraid of the unknown vocabulary in Bigbook, what should be the next step?
