Break one of the corner squares first and crouch so you don't fall in

And don’t dig the center block or the school will become a crater

Uhh where's the purple block..?

Sure

Simply break a corner square, drop down, break the block beneath the pressure plate, break all the tnt but one, place the plate back down, set off the remaining tnt to break the chests, then colect the items! Simple.

"Dig" is my middle name
