P6 Help

Hello all,
i failed in p6 and all i know is that i completed the book but i was unable to complete the kit properly,
but however i am confused what should i do next.last time i completed the kit till “Section A”… and dint touch “Section B”. what i cannot decide is whether i should take classes or not as i studied myslf last attmpt.I took classes half-way.after that i studied my self as i am a trainee.I found that i could understand concepts by reading the book.and i understood completely.but i guess its the practice thats lacking..i think so?

can u ppl take me out of this misery about how to go about p6 as i am going to reattmpt.
