Maths has always been the tricky part of the GMAT. The Questions appear to be simpler than they actually are! Yes, this requires some special care and a high level of concentration.
Books that I used -
- Basic GMAT mathematics fundamentals from Princeton review and Official Guide 11
- Kaplan 800 - Good collection of problems
- Permutations and Combinations, Probability, Statistics from class XI and XII mathematics text book
- Official Guide 10 and 11
The key to success in this section depends on your
- Basics

123 strategy as defined in my earlier verbal strategy post applies for this section as well. Here the 123 becomes 1234 where 4 stands for Concentration
