Frustrating day today.

Tried to do the annual enrollment thing for health insurance and so on, but the network refused to recognize that I was logged on.

Student came to class wearing a mask. I asked if she was feeling OK, and she said, "Yeah, I tested positive for Covid on Monday, but I met all the requirements to come back to class." So, I put on my N95.

I had to send out exams for high school students taking my online calculus class. I email the exams to teachers at their schools, and those teachers print them out, supervise the students taking them, and then scan them and send them back to me. I can't just send the same exam file to each one, because we use a system where each exam had QR codes on it, so I needed to be careful to send the right exam to each person, and to make sure not to send the same file to two different people. It took me a while to get the individual emails put together and the files attached and to double-check that I'd matched up the names and the files correctly. And then one of the teachers emailed me to say that she couldn't open the attachment. I checked, and none of the files had downloaded to my computer correctly, which meant that none of the attachments were right, and I had to redo the entire thing, after downloading each individual file (I'd done it as a batch before, which apparently you can't do.)
