Single or both groups of final

Hi Friends

I need your valuable advice for decision making. I had give 3 times second group and 1 time 1st group. I have good grip on law and audit in 1st group and indirect tax and isca in second group.

At present have covered more than 80% of audit and law and targeting to complete 1st group by month end.

I need advice whether should I go for both groups or single group.

Please suggest thanks in advance 

Thanks
