I used both. I finished the PR grammar smart over a period of one week..spending around one hour a day. I didn't revisit the book often but highlighted topics that I felt supplemented MGMAT SC
. I would suggest that focus more on the OG problems...rotate them repeatedly, each time eliminating all wrong answer choices and reading the OE.
Some of the 1000 SC problems are vague...use them for timing practice, don't worry about the hit rate. I always made 3-4 mistakes in a set of 25.
which would you say is better grammar smart or manhattan sc?
would it be worth my time going over grammar smart if i have already done manhattan sc? much overlap? thanks!
