GRE words

I have a question regarding GRE words. I have started preparing GregMat’s verbal mountain, I am at list -8 now. But when I am trying to do ETS material (Bigbook, ETS GRE verbal & ETS official guide), I find new words, should I make a note of each and every word which I don’t know and learn them.

One more question, I didn’t cover entire Gregmat word list as of now, If we compare Gremat list vs ETS material list, will most of words match?

Just take a note of them for now, you don’t need to try and memorize them yet, just focus on the vocab mountain for now.

Quite a lot of them will, once your done with the vocab list from GregMat, go through your notes and cross out any you learned in the vocab mountain, then try to memorize the rest by creating a new list.
