Applying strategies in right manner

Hi everyone

How should I ensure that I am applying gregmat verbal strategies in the right manner? How should I track my progess whether I am going in the right direction?

Use Big Book → To timed practice then look at how Greg solves them at https://old.gregmat.com/course/old-gre-walkthroughs.(can do same thing with the HW)

Hi, this link doesn’t work. Even I tried to find the old gre walkthrough videos but it is unavailable now.
