Today I passed the Microsoft 70-270 exam!
I used the MSpress book, Practice questions from a pdf my instructor gave me, and the CBT nuggets.
Definitely not a walk in the park in my opinion.
The funny thing is that when I got to the testing center there server was down. I guess Prometric did some sort of update just before I showed up and it somehow made there server freeze up.
I'm really excited about the pass because I surprised the people at the testing center when I told them my age and that I'm still in high school. It's really going to pay off having this cert when I go to college. I feel extremely lucky... 

I suggest to anyone taking this test to study for hard for at least 2 weeks before taking the exam. I studied for an entire month for this test and received a relatively low score. (but hey at least I passed and thats all that matters)
