Maybe I should say in this way:
For WSAD related certificates:
Among 285, 286 and 287, I do feel that 287 is more easier than 285 and 286, as the IDE related stuffs really make me painful to memerize, just like the plain old MCSE in NT 4.0.
Amoung 287, 484 and 486, I do feel that 287 is the most difficult one, as questions in 484 and 486 are more general.
Hope this help.
