Is it worth going to a more expensive college (extra 10k/year), if you can afford it?

However, what is important is to find out whether delayed graduation is due to student-caused reasons (e.g. school is not that selective, so that weaker students cannot handle full course loads, or fail and need to repeat courses), benign reasons (e.g. co-ops), or school-caused reasons (e.g. poor advising).
