4 months for both groups or one?? without coaching..

sir ,

according to me u should go for single group, due to the limitation of time.

try not to burden yourself by taking the presurre of both groups.

your efficiency may be harmed if you appear for two grps at a time

ofcourse, both groups have their own advantage, but consider the issue of time management and bulk of syllabus before coming to any decision.

Agree with Gyati.

U should go for 1st group only and devote your available time to that group to ensure that u clear that in the upcoming attempt.
