What is a "personal tutor"? On Workplace Stack Exchange, one answer to the question
https://workplace.stackexchange.com/questions/124329/bullying-group-work
says "Speak to your personal tutor. Immediately."
I remember to have seen the word "personal tutor" also here on Academia Stack Exchange. (As I do not remember having seen a country mentioned (also not on the linked Workplace Stack Exchange question), I believe this is a US-concept.)
So: What is a "personal tutor"? Who is this (undergraduate student, graduate student, administrative personell, post-doc, professor, somebody not related to one's university) and when do you as a student get such a tutor? What are their roles?

Thank you!
In the UK, a personal tutor is assigned to you when you start your degree and the same person will generally maintain that role for the whole of your course. They are usually a lecturer or more senior-- never a student, PhD or otherwise. There are often a mandated number of meetings that a student must have with their tutor: once a term is common.

The role of a personal tutor is mostly non-academic. While you could discuss academic problems with them, they are really there to help with pastoral matters, such as wellbeing, or helping you to decide what courses to take or how best to manage your time. Personal tutors are a common choice of reference letter writers for their students' applications for postgraduate degrees, as they likely know the student and their grades very well.
