Passed 70-270 today! quite a few tricky random questions in there so didn't feel too confident by the time I got to question 50, massive smile on my face when I see the word passed!

So, on to 290 now then!
Couple of questions.
Is the 290 similar to the 270? thinking of doing some hardcore studying and just going for it.
I'm in two minds on what study material to go for, used MS Press for the 270 exam but I feel it left out a few important subjects, IIS being one of them, I've heard the Sybex books are pretty good, whaddya reckon?
One last thing, thanks to everyone on this site, it's a real goldmine of useful information and I'm very glad I stumbled across it.
Thanks,
Rich
