I've completed my FOI, CFI, CFII written exams (did well on them - 98%, 100%, 98%). I originally wasn't planning on getting my AGI & IGI, but I've decided I'd like to do them. I probably should have done the AGI with the CFI written and the IGI with the CFII. How different are the AGI/IGI from the CFI/CFII? Should I just go take them?
