Hi Vikas,
I recommend short timed quizzes.
The best way to practice pacing and speed in not with full length tests. Rather, take short quizzes. Give yourself about 2 minutes per CR, one minute per SC, 4 minutes per passage, and 1.5 minutes per CR questions--do practice in 10-15 minute increments. It's very hard to learn proper pacing from a full CAT, because if you make timing mistakes at the beginning of the verbal section, you won't get feedback till an hour later when the section ends! But once you can do 5 questions in 10 minutes and 10 questions in 20, an entire verbal section isn't too far removed.
Hope this helps, and best of luck prepping!
