Asking your college advisor for a LOR

My college is mostly taught by TAs, I had one professor (for my program specifically) in my 2 years here. Mostly because I’m just now reaching the 400+ classes.

I am attempting to transfer to to UW Madison with average grades and good essays. Exceptional compelling essays for the unfortunate.

The website says a faculty member or advisor. Can a TA work? Advisor? Senior Lecturers?

My advisor knows me the best. We speak often and she knows my academics well Because we keep in touch for most things. I want to ask her but feel like she’ll say no cause she’s not a teacher?

My only professor(highly reputable from big name colleges)I got a C in his crazy hard class(algorithms). He’s also the chair and I also work under him teaching computer science.

When I say crazy hard, he literally tells the class if you get a C in his class consider yourself good, B and your above good, A and you’re hot stuff. Just not sure I want to ask him. Yes I know I work for him.

My advisor wrote a recommendation for me. He was also my teacher for a course but we had a strong connection. I would say go for it even if she says no it can’t hurt!
