Should i quit?

I passed my PE2 in 2008,1st group in 1st attempt and 2nd in 2nd. I was an above average student throughout. However my bad time started after opting for a mid sized firm for articles,where work was enormous(4 listed companies,many big foreign companies,among others) but no defined process nor they left us with time for classes. I missed my 70% of the classes. Then in november 10 I started giving attempts for final and is still in the process. Due to changes in scheme(PE @ to PCC) many people who passed 12th when I entered final are CAs n I am still stuck with the 8 papers. Everytime I fail becoz of one subject in each group,everytime I get 2 papers with near to exemption marks and winds up with 380+ marks. After exams I have been searching for jobs but to no avail,even after having more experince and knowledge than most CAs (no offence).This time also Accounts an DT have not gone well,and I am not so sure again.  But should this be my last attempt? I am going to be 27 soon and still havent earned properly,feelingall the hopes put on me have been dashed. Just tell me what to do.
