Because of a personal situation, I'm currently unable to attend most lectures (lately none) of a particular math class. However, I have a friend in my section who keeps me updated with the material covered, homework assignments, and exam dates.
I had previously spoken to the professor, explaining that I might be missing sessions throughout the semester, and she seemed understanding; lately, however, I stopped going altogether, and I've exclusively shown up for mid-term examinations (on which I do ok). To my surprise, I've been able to teach my self quite well, and, given that it saves me a considerable amount of time, I've been thinking of adopting this practice in the future.
My question is, given attendance isn't compulsory, would professors mind this, or develop any kind of resentment toward students who engage in this behavior? I'm a third year undergrad in a public university in Texas.
I'm not really sure whether this question is off-topic for this stack, so I apologize in advance if it is. Please feel free to change the tags as appropriate. Thank you
