Status on OG-12

I have 80 PS questions and 40 DS questions to be done on OG-12. I'm going to work simultaneously on OG Math Review, because my target is to complete the OG-12 by the end of the week and atleast 150 questions from OG Math review by the end of this week. Next week will be spent of doing the remaining 150 questions from OG Math review and I will be focusing on the error logs and verbal. I've been ignoring verbal for a long time now.
