Not sucking at scheduling would also do wonders.
Also, some space to interact with the topic the way I want. Tell me whats needed by the end of the semester and let me study for it my way.
As a professor, I so wish we could do this more. But realistically, it seems that we just can't afford to let students fail who aren't yet equipped to learn that way. But I do try to allow for this while still staying within the bounds of fairness, for example, giving students a grade based just on exam scores when that would be a higher grade, so they can blow off homeworks that other students really need credit for to shore up their grade.
This is a failure of the system tho. It's my understanding that e.g. in Czech Republic failing actually isn't a big deal as you can retake the exam (same material, different actual exam) shortly after the first one. This can make a huge difference.
I can go into more detail. I realize that things probably won't change but small changes can have big impact.
