Follow the timetable
This is of utmost importance. Many would make the timetable, but following it would be a difficult task. The moment you feel like neglecting the routine, remember the image that you had in mind of clearing the GATE exam and go back to it. The routine is going to be your guiding force till you complete the exam. Please do not cheat on it. In fact, what you can do is have a small competition with yourself everyday, where you challenge yourself to complete the course in fewer days than been specified in the schedule.
Use hundred when there is a specific number, and use hundreds when you don't know or can't count how many. This rule also applies to thousand/thousands and million/millions. This skeleton is thousands of years old. This skeleton is three thousand years old.

Seven thousands, eight hundreds and twelve
$10,000,000 = Ten million dollars
