You go to Case Western, right? Or is it Carnegie Mellon? I get confused between the two. If you go to school in Cleveland, a buddy of mine just joined the faculty.

Case. Not sure if I'll stay here after this year, though.

What department is your friend in?

I had a history class once where the entire grade was based on a single paper due at the end of the term. I didn't turn the paper in. I got a B.

Man, that takes me back. Way back to junior high (now called middle school) where they had a PE teacher teaching the required science class. Our grade was also based on one paper, subject of our choice. I worked my butt off on a paper on history of surgery but only got a B because the teacher admitted it was over her head so she didn't read it.

I loved college calculus - all of a sudden all the formulas that had been thrown at me in chemistry and physics made sense. But every damn test I'd make some silly error and get a 98. I swore one day I'd get a perfect 100 on a test. So one time I finally avoided every silly error, got a perfect score, but the prof had made an error and test test was only worth 99 points. So I still did not get my 100!
 
I took my math departmental math final yesterday and that shit was so easy compared to his tests. 22 of the questions were multiple choice and the other three were open ended. I'm not sure about the open ended questions but I think I got all the multiple choice ones right. The three open ended questions where something like if $4800 dollars was deposited today how long would it take to grow to $28,000 if compounded continuously at 7%, what is the vertex of so and so numbers (I would have gotten this one right but I was out of time and forgot the put the first number back into the equation to get the second number, Do'h!), and the last one was crickets chirp at 140 per minute at 70 degrees and 168 per minute at 80 degrees, what is the temperature if they chirp at a rate of 150 per minute.

But it sounds like the limit as your number of tests taken approached infinity was 100, so it's pretty much the same thing, right?

This question is obviously set in a parallel universe where getting 7% interest is possible. Presumably a rip in the spacetime continuum makes it possible for us to observe the other universe, so time is elastic. You already have the $28,000, you always have, and always will.

what is the vertex of so and so numbers (I would have gotten this one right but I was out of time and forgot the put the first number back into the equation to get the second number, Do'h!), and the last one was crickets chirp at 140 per minute at 70 degrees and 168 per minute at 80 degrees, what is the temperature if they chirp at a rate of 150 per minute.

Were you told that cricket chirping is a linear function of temperature? Otherwise there is no way to answer.

Yeah, we were told something about scientist discovering what a appears to be a linear connection between chirping and temp and to figure out the equation before solving.

To tell you the truth, I didn't spend much time on the open ended questions. All 25 questions were worth 3 points apiece and if you didn't write every step down perfectly, write down the answer how they wanted it (Vertex = 4, 19.5), and boxed in you answer then you couldn't get the full 3 points but you got a point if you wrote down anything. Not the mention two of the three questions were very time consuming, time I felt I could be spending on making sure my multiple choice answers were correct.

Only as the tests approached infinity. Fortunately I did not have to take that many!

I'm with Barfo on this one.

It also reminds me of a test I had to take when applying for an engineering position coming out of the Navy. It was a complicated, potentially-trick thermodynamics question. I decided that since I had already taken the afternoon off for the interview, to be kind of a show-off and go into some depth about stuff I'd learned and studied for my DoE Nuke Exam. The proctor told me that I'd missed the question, and he'd never heard of the equations I'd tried to "make up".

At that point, I withdrew from consideration for the position.
