Standards on Auditing

I m appearing for forthcomming PCC exams n i downloaded standards on auditing from share files... m afraid they r not enough mean in sense of explaination .....

so my question is it sufficient to have basic knowledge (i.e not as deep as posted by institute ) of the standards.....

last time i studied only AAS n my concepts were clear based on that study only...n i managed to score 58 last time but this time m getting goose bumps thinking of auditing.
