I've been a GMATClub browser for a couple months now, and wanted to actually start contributing instead of just watching. Anyways, I wanted to let everyone know about these videos that I found. They are the best explanations for the OG quant
questions that I've found and have helped me tremendously in my preparation so far. Methodical, clear, easy to understand. I can't believe I haven't seen these linked on the forums yet. I think this guy deserves more traffic.
Hope they help all of you as well!
