Teaching is a tricky business, especially when you face diverse student body. For core classes, you don’t have much choice—you have to water down the content, because of student teaching evaluation. For electives, you need to screen the students so that only true fans will take. Then you will have an easy ride.
Regardless, you must strike a balance between rigor and likability. Too strict, you turn them away; too loose, they won’t work. You must understand learning is a two-way process, and not every student is willing/able to learn, because that takes intelligence and effort.
I had hard time to deal with undergrads. Removing the final is a mistake. Without accountability, lazy ones have all the reason to be lazy.
I will have the final for all the classes I teach—we are all accountable for our actions.
For teaching, you must change your attitude—it’s all about making them happy. Remind yourself every time when you teach and answer their questions.
You are irrelevant.

I should have canceled all classes in the morning. I know teaching will worsen the situation. But I was worries about the consequences of canceling class with short notice. So I went to school anyway.
It was exactly as I expected. After teaching two classes, I was drained and caught fever. I had to cancel the rest two classes, in even shorter notice.
Next time, set your priority right: if you are sure the cost is more than the gain, just cancel it.
Using the debugging technique, I finally fixed the font problem (delete eta in the last theorem) and submitted successfully. The problem first appeared in Dec. 23, and has been around for 17 days. Had I worked out intensely, it would take only one hour to fix.
Next time, pay fucking attention.
