You joke, but I recall my graduate level GR class homework. Just mechanically writing out solutions (the GR equivalent to writing the correct integral down and then evaluating it) to a much less exciting problem, starting with the most basic mathematical representation of the tensor field(s) involved would take pages and pages of handwritten work. It’s a fascinating field.
