Passed PSM without studying for it

Well I guess that isn't exactly true being I've been studying for PSD for 7 weeks
I passed PSM on the 1st attempt unlike the 3 needed for PSD

Passed the PSD on the 27th and the PSM on the 28th - there was no additional preparation for the PSM

I strongly recommend the Star Scrum Academy practice test for PSD and especially for PSM
it is a well invested 10 bucks

Passed PSD today - 3rd time is a charm
