As per my experience if you are just starting GMAT preparation, do not keep pacing with time..first try to understand questions, their explanation including wrong answer's explanation etc...and down the line after few weeks once you see you are correctly doing all those questions, then ONLY keep pacing with time and which would be then a 'MUST DO' activity...

Also see other's comments and keep judging yourself about which strategy really fits with you..it's not true that one specific strategy will fit to everyone..

Hope this help.

I would just like to add a point here. Normally, people practice with OG multiple times, atleast twice. First time, you should only concentrate on the strategies, how you would solve the questions and what different approaches you could come up with each problem.

After practicing non-official materials, if you have any, you must come back to OG and do this again BUT under timed conditions. This practice is for pacing under limited time.

Two key points,
1. You should never try to memorize OG questions anytime. Otherwise, when you practice for the second time, you will immediately come up with an answer without even reading the full question. This will produce skewed results that will not help you with your preparation.
2. Maintain an error log whatever mistake you do while practicing with OG. After complete practice, redo the wrong questions until you are familiar with the concept.

Hey Papgust, Tell me one thing, How should one try not to memorize...I mean, is there any way we could forget/release specific portion of information from our memory? I would be happy to know the way to forget ..

Unfortunately, i'm not doing any research study on how to release some portion of information from memory.. You better consult a neuroscientist.. Just kidding!

so that means you added one more stuff to get success in GMAT, visiting neuroscientist as well... Guys,... when visiting neuroscientist pls ask backup of your Quant and Verbal section before knowing how to release memory. he he he....
