Having set time limits for each of the sections that appear in CAT, you need to ensure that your progress is keeping pace in the set time limit.
From my experience of following the last few five or six CATs, I believe that attempting 85 to 90 questions in CAT and getting over 65 as net score is a definite recipe to get calls from couple or more of the IIMs.
With 120 minutes at your disposal, the arithmetic essentially translates to about 7 to 8 questions every 10 minutes. Therefore, divide your 2 hours mentally into 12 slots of 10 minutes and at the end of each 10 minutes do a status check. In reality, you should be doing better in the first half of the time allotted to each section in terms of the number of questions attempted (over 10 every 10 minutes) than the second half. The reason is that you are expected to attempt the easier questions that consume less time in the first half than in the second half.
If you find yourself slipping in any one slot, you need to buck up in the next couple of ones to maintain your average.
If you are in the habit of using a stop watch, make sure that you start it as soon as you get the signal from the invigilator to start the test. There have been instances of students getting tensed on account of not starting their stop watches.
