Hi megha_2709
You've received some good tips here so I'll keep my tips general. Here are some general do's and don'ts on time management:
-Do know that it’s OK to take longer than two minutes on a question. Just make sure you counter-balance this by taking less than two minutes to answer other questions. But...
-Don’t ever take four minutes or more to answer a question. It is tempting to try to answer each question correctly, even at the expense of time, but this strategy will likely hurt your score more than strategically guessing at several questions will.
-Do use a clock or timer to strictly keep track of your studies while practicing. You will soon know what a ten minute stretch of time feels like.
-Don’t constantly sneak glances at the clock to look at the timer. Work in clusters of five questions (each cluster taking 9-10 minutes) then check the time.
-And finally, do remember that time can feel very different in your head while concentrating than what actually appears on your clock.
Hope this helps. Best of luck on exam day!
