I am sure you have been checking the CAT official website every day. Sharing the communication from CAT website on normalization:

CAT 2014 shall involve administering a different Form of the Test across each of the 4 different Test Sessions. In order to ensure fairness and equity in comparison of performances of the candidates across different test sessions, the scores of the candidates shall be subjected to a process of Normalization. The Normalization process to be implemented shall adjust for location and scale differences of score distributions across different forms and the scaled scores obtained by this process shall be converted into percentiles for purposes of shortlisting.

For purposes of reporting, Scaled Scores for each Section (Section I: Quantitative Ability and Data Interpretation, Section II: Verbal Ability and Logical Reasoning) and Total along with the Percentile shall be published.

The process of Normalization is an established practice for comparing candidate scores across multiple Forms and is similar to those being adopted in other large educational selection tests conducted in India such as Graduate Aptitude Test in Engineering (GATE).

To know how normalization works for GATE, please check this Wikipedia article. Very well explained (with formula). You will get a fair idea of how normalization is done. All the best for CAT results. Keep us posted.
