Some number theory, linear algebra, calculus of variations, combinatorics, etc. From the applied math side of things, it isn't terribly deep. It's actually right about what I would expect from an applied math student who was good at the undergraduate level and ready to study at a competitive university.

For general admissions for any discipline though, I'll agre it's probably a bit rough for non applied math grads. At least it doesn't include any analysis, abstract algebra (groups, rings, fields, etc.), or topology. Which would be murder for non-math majors.
