It could be really useful for this exam.
But you can find the correct answer (for those questions) also without a calc. It take little more time
SAY WHAT! A calc app?!?! Awesome. I wish it had been there when I took it at VMworld. Not biggie since it only cost me $100 but I think the lack of a calc is one of several reasons I didn't get through that time. The other reason is that I should have taken my studies more seriously.
Retake in just over a week.
