For a multiple-choice exam, administered electronically to dozens of test-takers supervised by one proctor...is that actually reasonable? Plus they charge you $15 extra if you want more than 4 scores. Most students apply to more than 4 colleges. Are they physically mailing scores to these institutions?
For a mostly-electronic process (other than the essay grading) $65 sounds like a lot. $40 for the non-essay option sounds even more crazy.
I'm sure it's not trivial to make multiple versions of the same test every year where the scores are all comparable with each other. then you have to distribute the materials while minimizing the chance that they leak and people come in with the answers memorized.
the college board itself makes about 15% profit each year. definitely a lot better than some market segments, but hardly exorbitant. I guess they might find some ways of trimming the fat if they had more competition, but who knows. more competitors means fewer test-takers to amortize the test design costs over.
The issue is not with the college prep companies. It’s with government getting involved in education, making it way more expensive than it should be. The free market will drive prices down, especially in the education market.
People want to pay thousands of dollars to try to gain access to elite institutions. No matter what test you'll come up with, someone will offer an expensive prep course for it, because they will have willing customers.
