Question: Do you have accounting background (knowledge), or have you studied Accounting before?
I would advice you to register after giving yourself a chance to properly study, do not take the exam for granted, rather take the next sitting because 1 week is insufficient time to prepare for this exam.
Do you mean if you study 24 house a day for a week?
No you will not.
Be sensible and study properly, they are professional exams and they take months.
