I plan to take the 220-701 and 220-702 exam in January, already been studying hard for it. I heard that the 220-801 and 220-802 exams are out, and is there a big knowledge gap between these two exams? Will people who take the 220-801 and 220-802 have an advantage over me and should I learn that information after I pass the 220-701 and 220-702?
