While the notification for CAT 2015 had come out on 26th July, there was still a lack of clarity regarding the order in which the sections would appear in front of a candidate. It seems that CAT has put up a bit of information on their website which would clear some doubts (or probably create a few new ones).
This is what the FAQs section on the CAT 2015 website says:
While there isn’t any logic or intent specified with regard to the new bit of information, probably as always, it seems that candidates are supposed to digest this bit of information without questioning the rationale behind it. We shall come up with a post to evaluate the impact of this on the test taking strategy soon. Keep watching this space.
All the best!
