the more you practice and the more timed sections you do, the more efficient you'll become. by the time test day comes around, the "time factor" won't be at the forefront of your mind like it is right now. you'll instead be able to concentrate fully on the questions themselves and not on how much time you have left to complete the questions...do as many CATs as you can. I took a course with manhattan review
and they provided CAts as well as a ton of great tips and tricks for how to conquer the "time factor".
