The military has some interesting ways to motivate students. I did the math and found out my naval electronics training involved more class hours than a full 4-year degree, so when they say it's equivalent, they're not far off.

You're tested every week, below 75% is failing, and if you consistently fail, you're sent to the fleet to chip and paint. That keeps a student motivated through the driest of subjects.

Which is good, because multivibrators aren't nearly as interesting as they sound.
