Well this is my first post and I thought I'd start with some good news. Passed today with a 794... not the highest score but I've learned some lessons about how to study... I really only went through lots of practise questions, including the ones on here, and anything I got wrong I just read a bit about and did more test questions.
For the 70-290 I will be getting a sybex study book (or similar) and read it cover to cover and actually carry out the labs, even though this test may overlap the 70-270. I struggled with this test as I basically had to rely on educated guesses on some questions.
This site was very helpful so thanks to all
