Took the exam today, 10 AM CET, and passed after about 2 hours, with a score of 871. Which is the best score I've ever gotten on a Microsoft exam.

I used the following study method:
Read through the training kit two times, doing all the excercises.
Read through it a third time, wrting an exam cram, and did all the excercises again.
Used the exam cram to do all sorts of practice labs.
Took several Transcender test exams.
Onwards to 291, time to slay the beast!

Thanks to everyone who gave advice on questions I was wondering about.
