In a mess... urgent pl help

hey all i passed my pcc in may 12, planned to gve only 1st group in may13 as till nov12 i didn't got any classes. nd n may 13 exams to be true i went BLANK in SFM paper, so i already know what iam going to get as my result. now the issue is should i take classes of 2nd group now or not???? 
while some people are telling me not to go for any class and concentrate on 1st group and while some are advising me to take costing and idt right now.  
the thing is i won't at all give both groups together as i can't manage both and even thought i cleared my pcc in may 12 so  actually know my worth..

people who are advising me to take 2nd group classes are saying that i will most probably be wasting my time till the result comes even though i know what the result is ,so its better to go for atleast 2 coachings now as 2nd group ki classes can't be done in 6months. 

so iam confused. pl pl help
