I just attended the structures webinar and there appear to be a mistake in the answer to an exercise that we were asked to respond to. Specifically formula for Mmax on uniform distributed load simply supported beam. wL2/8.  
In the answer, it showed w.L then it was squared. This is wrong. Only the L should be squared. Otherwise the formula will be (wL)2/8. It makes a big difference.
