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.

I don’t know. I haven’t tested for anything. Cough, fever, sniffles.
Same symptoms here. I'll do the Covid test tomorrow.

And? I was Covid negative last night.

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?
Only non-witches get due process.

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.
But maybe we could ask Mr. Musk if he could take a moment and cut a few threads.

How do you do that comparison?
Just the first post in this thread tells the story. There were no active threads for most of the day on Saturday. Even after Jon’s thread, it never got busy. Today? This place is slamming’…
