Yes, actually. That book is fantastic. He explains things, then gives you a drill, then some more test like problems. Everything is clear and organized and specific. It's worth every penny!

OG Diagnostic question #10 (star)

I searched the forum but didn't see anyone asking about this one.

I read the explanation but I still feel like this one would take 20 minutes on the test if you did it that way..... Does anyone know a faster way to do it? thnx
