I'm now starting to study for my MCSE exams. The exams that I need to take are as follows: 70-270, 70-214, 70-215, 70-216, 70-217, and 70-220. These are the required tests for the MCSE with the security specialization. I know that I will be taking 70-270 first, but after that I'm not really sure which test should be next on the list. Well, I'm assuming it's 70-215, but after that I'm definitely not sure

. Could someone give me some advice as to the order I should take these exams, as I am quite sure that most build on knowledge gained from the previous exams. I'de appreciate any input you guys might have.
Thanks,
Cheeblie
