I canβt really comment on the comparative merits of doom vs scool wrork. Iβd need a time machine to get some more experience with the latter.
My only datapioint is that I passed the exams, so doom must have some teaching ability.
I shoud also credit wing commander 3 (with pixellated luke skywalker in the fmv cutscenes) - that was also a big part of my gcse revision plan.
