MCSE 2000 Help

I am currently in school trying to get through the MCSE 2000 course (among others). I have taken the 4 core courses and have only taken the 210 (Professional)test. My problem is that I want to take the 217 test then the 216 and last but not least, 215. Obviously, out of order. The school doesn't want to let me do that but if I have a good argument for it I might be able to convence them. I haven't written to Microsoft yet because I thought it really doesn't matter if the core test are taken in order or not. Any help with this line of thought? Btw, I am more preped for 217 right now than for 215. Thanks....
