Ca final exam group selection

Hi m so damm confused, i ve cleared pcc in 4 attempts.2 days before i got my result i was hired by one of d big 4 ,though not so good profile,nt that challenging but yes where peace of mind is guaranteed.now i want to take final exams,i m not at all ready for both groups ,but think i can try for one group considering i ve off on weekends, can we take second group before i take first group Is it advisable.
