Katy Perry - One Of The Boys Chords

I tabbed this from her live KISS FM performance which helps with the strumming. 
Some chords are variations but since I'm not that fluent with all my chords and
notes and what not I'm not sure what to name them. 
But I think this is pretty close to the song so if you have any comments or
advice feel free to share. Thanks ;P
Capo on first fret
