I just update the Classroom file with little closer match. Their is always going to be some difference between Cycles and Eevee. In this scene Cycles is using a light portal on a window which a little harder to match in Eevee.
My main goal is to push Eevee to create realistic rendering specially in ArchViz.
If your are interested I have a number of Eevee realistic ArchViz scenes that I have done from Cycles. See my ArchViz series at this link Realistic Archviz.
