I recognize those doors because we had the same doors at my boarding school. Those doors might as well be made of steel. If it's anything like the doors I'm thinking of you'd probably break the bones in your leg before you actually kicked it open. As far as I'm concerned you're probably not getting in without a lockpick, a battering ram, or window access.
I have gotten into a second story room by asking my neighbors to let me climb out their window, but those were small rooms where the windows were very close together, and you might like, fall. But hey, if you get seriously injured, you could probably get an extension on that project right?
