    Took my first Calc 2 midterm this morning, in my all-online class. They have interesting systems these days. First they have a "biometric" ID system where you show your driver license to the webcam, then use your mouse to "sign" a password. You repeat that signature a few times, and then they make you provide that password before the exam. You have to use a special "lockdown" browser which takes your whole screen and prevents you from opening any other windows. Before the test, you sweep your room with the webcam to establish you don't have cheat sheets on the walls. Then you keep the webcam trained on your face for the whole test. There was a two hour time limit and it was brutal. 19 mostly non-trivial questions, so I didn't have time to ponder. Either you are perfectly fluid with the techniques, or you are toast. Filled up five sides of 8x11 paper. I got through all of the questions, but I know I missed at least one due to haste. Hopefully that's the only one I missed, but I am not betting on it. It will be interesting to see the curve. The online grade system gives you a grade distribution, like where the quartile cutoffs are.

    That is a challenge.

    It seems like there must be some holes in that system.

    They need some of those glasses like Tom Cruise has where the guy in the truck can see everything that Tom sees.

      Fucking hotels.

      I normally just use the ice machine down the hall and/or water from the tap. In North America and Hawaii that is. Elsewhere, always bottled or boiled water.

      Yeah but when you’re sick enough you’ll pay $9 not to do that.

      True enough. I recall being there in a hotel on at least one occasion at the end of a trade show.

      Came down with an influenza that flattened me for at least four days. I lived on room service deliveries of French Onion Soup and black bread and carafes of coffee. Luckily it was one of the better western managed hotels in Moscow at the time. No way though I could travel and had to rebook a flight to Cyprus leaving me with only one day to spare on my 3 year multi-entry visa before expiration. At the time I had to go to Cyprus to get my multi entry visa extended for at least another 90 days at which I time would go back to Canada and, among other things, get a new visa.

      I recall it all very well because during those fever ridden down days in the hotel room, that right wing terrorist and nutter, Timothy McVeigh, bombed Oklahoma City.

      Elbows up!

        I was driving from central CT to central Jersey to be the best man in a friend’s wedding when that happened. It happened early in the drive and I listened to live coverage on NPR the whole day.

            Oh, it would be easy to cheat, even with their precautions. I am sure some students do. Could just flip the keyboard and monitor to a hidden laptop, and use online tools to solve the integrals and derivatives. They provide the whole step by step solution, not just an answer, so the scratch paper will still look good. The webcam can't see your monitor.

              I don’t know. I haven’t tested for anything. Cough, fever, sniffles.

              The boy had something similar S-Tue, but I flew out Tuesday and this hit me Friday afternoon. He was Covid negative.

                          Good news and bad news about my test score. I got a 95, because the professor is reasonable with the partial credit. In a five point problem, if you made a calculator error at the final step, you only lose one point. This is how I scraped by with the 95. Bad news is that the whole class did well, with a median score of 89, so the time limit apparently wasn't an issue for very many people. I'll have to recalibrate how fast I go on these exams.

                            That is good. It proves that you know "how" to do the problem. That is more important than getting the right answer buy not understanding how you got it.

                              Just curious, Horace, how does o3-mini do on that test? Or any other reasoning model?

                                @jon-nyc Mosty standard derivatives and integrals, so I guess pretty well. For instance, https://www.symbolab.com/solver/integral-calculator is able to solve any of them, though that's a hand-written system of logic rather than a generative AI.

                                  I think I told this story once before. In high school calc, our teacher liked to give power tests - essentially tests that could not be completed in the time provided. Calculators hadn't been invented at that point in time. When we got to integral calculus I did the test but failed to add "+C", C being the constant. He deducted a point for every question. Next power test - I went through all 70 questions and wrote "+C" before starting any calculations. He have me partial credit for them - of course, that sparked some disdain from the rest of the class. The instructor assured us this was the last time he would allow that gambit. From my perspective, karma and equilibrium had been restored to my personal universe.

                                    @jon-nyc Actually come to think of it, that website can't do solids of revolution problems where you have to set up the integral and solve it rather than solve a given integral. It would be interesting how the AIs would do on those. Could try a slightly complicated one like "the volume of the solid of revolution about y=7 of the region between y=x^2 and y=x".

                                      That's well gamed. And the teacher accepted his loss gracefully.

                                          Nobody ever said this would be easy.
