how long did you prep for?
roughly how many hours a day etc?
I spent approximately 50-60 hours over 6 weeks for the exam. This was because I am not looking to apply to T1 schools and was looking to get a "good enough" score for my target part-time programs, and I had to factor in work/family/prep balance.
I did timed practices - 20-30 questions of each kind at a time, with average < 1 minute per question, and followed up on wrong answers. By the final practice test however, I was giving myself 2 mins per question. The only section I spent time studying on theory was for sentence correction, which was time well spent even for ex-GMAT life. Apart from OG, I also used the app from Prep4GMAT and would do 10 minute practices during the day at work. Its content is way tougher than the actual GMAT, but I liked their byte-sized tests.
