One more last question regarding CR+SC part.should i do chapterwise OG after chapterwise TTP? OR i should complete verbal part with practice test then i Should pick OG?
You may be best off using the OG verbal questions after you have gone through all of TTP SC and CR.
On a related note, you can spend a LOT of time on the TTP SC and CR questions. Don't seek to answer them in under to minutes each. Do your verbal practice untimed, and carefully analyze every choice of every question.
You need to spend time with verbal questions learn to see what's going on in them.
