CAT 2011: QuantoLogic Analysis

I finished my CAT 2011 journey in the initial phases. So did some other friends who are involved with us at Quantologic. Here is our analysis.

1. CAT 2011 is a tad difficult when compared to CAT 2010/CAT 2009.
2. The data intensive complicated logical reasoning questions have disappeared and the focus is more on basic understanding of problem solving techniques.
3. The onus is on the student to solve the easy questions.
4. Every paper especially the Quant and DI section has enough sitters for an average student to crack. We must also mention that every paper has around 6-8 difficult to very difficult questions which require analytical imagination.
5. Section 1 feels short of time, you need to choose your questions well and take no more than 2-3 minutes to solve any question.
6. There are some DI questions which require lengthy calculations, but the calculations can be remarkably reduced by making smart approximations and using the options well.
7. The number of Data Sufficiency questions have gone down considerably.
8. The questions are focused on basic concepts and formulae and one needs to be able to solve questions from first principles rather than imaginative methods.
9. Read each question carefully before you start solving and try to look at the options as some of the questions will require much less work if you use the options.
10. Overall an intelligent test.

Cheers!
