Age and Marriage

First complete your CA. Don't plan too much about life. Everything will happen at the appropriate time.

Shall I give one group in May 22 or both the groups in November 22?

Agree with kev

@ Hitesh
Giving 1 group or both or none should be your own decision. You can start by studying a all subjects of one particular group. If you thoroughly study one group and have confidence and time to to complete the second group, go ahead. If not, then just give 1 group. Don't study some subjects of 1 group and some subjects of group 2 because then if time becomes limited, there will be panic. It is better to give your best in any group rather than half-heartedly trying both groups. This is my humble opinion. It all depends on your judgment.

Shall I skip the May attempt and appear for both the groups in next November so that marks get compensated in total.

Also due to personal reasons I would be able to complete only Group 1 studies before May22.
