Faulty circuits

I'm now into the fourth week of an accelerated eight week semester, and after looking through all the b.s. and fighting a losing battle to my stress levels, its dawned on me that I have learned absolutely NOTHING. My professor assigns an unreasonable amount of work to be finished in an unrealistic amount of time. I can honestly admit to anyone that needs some sort of electronics repaired, look elsewhere. I have learned nothing other than how to turn in an ungodly amount of homework. Seriously, I'm so busy crowding short term memory full of complex equations, formulas, and other abstract nothingness, that I have no time to really take in, and fully understand anything. If tomorrow he asked me a question from something from the first chapter, I wouldn't know it. At any rate, I don't get it, it's all going way to quick, and I'm not sure I'm comprehending anything that is going on anymore.
