Physics

Our Physics class is using an online homework provider which is a real pain. For one thing it cost $70. Usually the service comes with a registration number on your textbook, but we got our Physics book used so it was useless. We got our Physics book used for $40 instead of $200 so we still got a pretty good deal.

Another annoying thing about the online provider is that you only have three tries to give the computer the exact answer that they want. Also, if you submit your answer it just says "WRONG." I like human teachers better because they say things like "Check your significant figures" or "Remember, the arrow is going THIS direction so the number is negative" or "See how it sits in the negative X axis? That means you have to add 90 degrees to get the REAL answer." When the computer says "WRONG" it could mean any of these things.

P.S. I haven't gotten any of the questions wrong. Yet. But the first thing our teacher did on Monday was give a little pre-lesson pep talk about not getting discouraged if you don't get all the questions right. Tis' an ill omen.
