Work experience for ca final

Its depends on your past performance, If you are average student, may be face problems. But if you had good past record. Good retaining power , catching power and ability to work hard and many other things matter.  I have seen many persons have very goods practical exposure but 

not able to pass the exam. Because ca exams is depend on how much you study and crame the syllabus and very few part required practical experience.

I have very good experience in company but failed many times. some of my friends have passed the exams but they were NIL during their practical training

Its all depend on your SKILLSS. I HAVE SEEN HUNDREDS  OF DUMMY CASES PASSED THE EXAMS VERY EASILY.
