Took 70-270 today and came up w/ a 653!

If it didn't hurt so much that score would be absolutely laughable!
I've been studying on and off for this test since December and in the last three weeks I easily passed 271 (900) and 272 (920) so I figured w/ a week or so of review I was good to go. I was consistently scoring 90% on the Measure Up practice exam that came w/ the MS Press book but when I got to the exam it seem like the focus of the test was completely different than what I expected.
I had numerous questions on specific GPOs which I thought was completely out of scope for a client side OS test. I also had a bunch of questions on RIS which I expected and some on security as well. There was not one single question on Control Panel or Task Manager and there were only a handful of questions of NTFS/share permissions. From what I recall there was one question on HAL ( dual processor ) and one question on hardware profiles.
For the most part this struck me as something of a "trap" test. The kinda of test when I was undergrad that loaded w/ "gotcha" questions designed to weed people out. I've been in IT operations work for 11 years and I've used XP exclusively at work and at home since it was introduced. I now see why many people save 270 for last and do the server tests 290/291 first. It seems like you'd have a better grasp of GPO after studying that stuff rather than just after learning the client OS.
At any rate, sorry for the rant I'm obviously more than just a little annoyed today! My question for the forum would be, how many other folks saved 270 for last on the MCSA track and is 270 easier after taking and passing 290/291? Relatively speaking, how do the 270 - 290 - 291 compare to each other?
Thanx for any constructive feedback!
