Hi guys! Thanks for your continuous help.
I will be studying GMAT from a combination of
MGMAT books and
OG questions. However, I also want to spread my 6 official GMAT mock tests from GMAT/mba website (I'll be buying them) in my 3 months time.
The problem is that I was planning to get my
OG questions from "The Most Comprehensive Collection of Everything Official" topic from souvik101990. And, from what I understand, this questions also include the Official questions from the mba website. Therefore, when it's time for me to do the mock tests from mba website, I will be running the risk of doing questions I've already done in the past, which would bias my results.
An option I have would be to only do exercises from
OG Books I buy or find online (since I believe they are non repeated from mba mock tests). However, it will be really hard to track which of the questions are new, since
OG Books repeat questions from one book to another (any ideas on how to track it to invalidate my conclusion?)
In short, my question is: how can I use all the available
Official Guide Questions without running the risk of biasing my 6 official GMAT mock tests from mba website?
Thank you!
