An online homework program designed to rob college students of their hard-earned money and serve as a crutch for professors too lazy to write their own homework assignments or to teach. Its purpose, beyond making millions for the publishing company, is apparently to reduce the number of engineering graduates in the United States by utterly demoralizing and destroying their confidence in an effort to force them to drop the program and/or kill themselves.
I used up all but one attempt on this stupid Mastering Engineering problem, before I realized it had switched everything to kiloOhms instead of Ohms! And then I still got it wrong! FML!
