Keep in mind that a typical course is 3 hours (in class) per week, where a bootcamp is typically 30-40 hours in class. Perhaps the expectation is that the hours difference is offloaded into "home work" but you often need to do additional work in a bootcamp as well. That assumed, given a typical course load, a "semester" of bootcamp is roughly equivalent to 2-3 semesters of college work.
