My GMAT is in 2 weeks and I have covered nearly all quant. However, I still struggle with number properties. I understand the basic even-odd/ positive negative problems, however I'm having real hard time with divisibility and primes. I learn through the
MGMAT books and tbh, the 5th book on number properties in the
MGMAT series largely went over my head (save for combinatorics/probability).
I even saw a tutor for the same but I guess it's just my bad luck that the tutor was very bad at explaining the concepts. She was great at solving questions but I couldn't really explain how to apply the concepts and approach the questions. I sat through a 3-hour number properties webinar by a prep company and most of it was just gibberish to me. Their approach was too formulaic and I just couldn't translate into real hard math that'd help me solve questions.
My question is, is there somewhere (on this forum or web, a guidebook, thread) something that'd help me tackle number properties as quickly and painlessly possible? Specifically, divisibility and primes? I believe my quant prep is complete save for this chink in my armor.
Thanks a bunch!
