"Each question paper will be a little different from the other, but its evaluation would be done on the same scale," Managing Director of Prometric, Soumitra Roy said.
"Since each question paper will be different, it might be possible that some questions are tougher than others. We'll keep this in mind while conducting evaluation," added Roy.
This along with other measures have been taken to maintain accuracy and impartiality while testing students in the CAT 2010 examination, the agency said.
The Common Admission Test (CAT) is held annually for admissions into the prestigious Indian Institutes of Management (IIMs).
The all-India test will be held across 33 cities between Oct 27 and Nov 24 for the academic year 2010.
Registration and scheduling will open on Aug 30 and close on Sep 30. Vouchers for CAT 2010 would be available for sale at select Axis Bank branches from Aug 30 through Sep 27.
Prometric will also be releasing a collection of short online videos to familiarise candidates with the registration and scheduling process, test day procedures and other aspects of CAT including the scoring method.
Videos will be available on the CAT website for candidates to review after Aug 30.
