Okay. I am a web applications programmer. I do Web Application design and implementation everyday at work.
It was no surprise to me that I would do somewhat alright on 70-305 (Web Apps). I passed the test with a 905, which I thought was pretty darn good. I recently took the Windows App Test and passed with a 950. I didn't feel fully prepared when I stepped in to take it, so it was more of a surprise to do that well on it.
I found it kind of funny that I earned a better score on something that I don't use day in and day out. In fact, outside of training I really don't make Windows Applications. I do quite a bit with classes and class libraries though. There were more questions towards this direction on the windows test that were not on the web test.
It's possible that the tests are nearly similar that if I prepared for one really well, I could probably have passed the other without changing much. Two things. (1) One test builds on the other. (2) When I took the first test, it was also my first Microsoft test ever, so I was concerned about the level of difficulty in the questioning techniques. I was less nervous taking the Windows App. In fact I felt very comfortable in there. It was almost better than I felt while I was studying.
You see I do this thing when I take the tests. For anyone that hasn't taken certification tests, they give you two laminated pieces of paper and two markers to take in the test room after they strip you of everything else. I use one page where I put down all of the question numbers. Then I mark the answer (and other possibles when I am not sure) and assess my level of sureness. This ranges from getting the “answer right” (+) to “not quite sure” (?) to “I don't have a f..ing clue” (???). Then when I decide to commit my answer on one possibility I circle that one on my “scoresheet.” Weird, yes? No. It gives me an idea of whether I am going to pass or not. The amount of plusses (+) directly relates to how much of a sweat bath I am taking while brain-draining. Of course I still have a whole other “board” to do any kind of doodling to help me solve problems.
That is what I do. It works for me. You can decide what works for you when you take the tests. If you like that idea and it works for you, too, let me know. That is a test-taking tip and doesn't relate directly to Prometric tests. Basically it is my advanced way of understanding, eliminating, and evaluating to find the best answer to each question.
Another tip? Understand the why and the how, and then study, study, study.
