I know Rakesh. As for me, I just cannot participate now because I'm out of time to do that. My next attempt will be in 6 months only and I can only focus on shorter problems now. Sorry Surat.
Hmm. If I recall from a past post, you are already at the mid 600's level, and now you are pleading "no time" because you "only have 6 months" to study? I think you need a more efficient approach to studying.
My advice would be to "take the time" and do a few longer problems in excrutiating detail, focusing on the learning process rather than repetition. As many on this forum will attest, I have always stressed "smart learning" over sheer repetition consistently.
If you are making no progress, or if your score has actually gone down despite doing lots of problems, then you may want to as least consider taking those few extra moments to grind through the longer problems and completely work through them (including understanding why all of the wrong answers are wrong and being able to articulate it in your own words), rather than going through the motions of another set of "short" problems.
