I think I see what happened. When you read, "Colleges differ," you took "you wouldn't be missing much" as the context. This is largely due to "So it is with colleges."
Earlier, in "Colleges are a bit like exclusive clubs" I think pg intended "a bit" to communicate that what he's saying about exclusive clubs is less true for colleges. Humans read differently from computers, and those two tiny words are easily lost. "So it is with colleges" dominates.
