Penrose goes beyond undergrad by some way, heck beyond some grad school, but you couldn't pass undergrad physics with it. (I did quantum mechanics and modelling but I was a materials science/ Molecular Biology major so the courses had an applied focus, and there was no General Relativity of course.)
His goal is more "be able to read a current paper on Calabi-Yau manifolds and understand at a very general quantitative level what the equations mean and what is being talked about" rather than "become a physics undergrad/grad school equivalent in knowledge". With textbooks it would be a good roadmap for a coursework masters level education though.
