How to review verbal questions?

Thanks a lot! these are very helpful.

Most of the time we know that certain option is incorrect. However unless you can give specific reasons as to why that option is incorrect you are not learning fully from that problem. The reason why a particular option is wrong may not help much on a specific problem but on a different problem the same concept can help you zero in on the right solution.Moreover one option can be incorrect due to more than 1 reason. When you look at how experts dissect a problem you would see that they have a concrete reason for every decision. Having said that Donot get hung up on a single problem. That is Donot spend 20 30 mins on a single problem. You can miss some concepts and still score 720.
