I read theory given in og for cr and did 40 questions and was able to maintain accuracy of approx 85% do i need to refer to powerscore or keep solving questions and analyse the mistakes?
Posted from my mobile deviceThough OGs are the best book to start your preparation with, but I would recommend you to go through the exercise if not theory of both
MGMAT CR guide and Powerscore bible. Track your accuracy accordingly, if you are comfortable with the questions given in both the books, you do not need to go through theory part, but if you see your accuracy plummet in either of the exercise of aforementioned books, going through the theory part makes more sense.
