Hello, OP - As an Oxbridge maths graduate you know this is misleading. ‘Challenging’ is not orthogonal to ‘nurturing’. Loads of support is available but one must go through channels.
Those channels include your PT and with a reasonable amount of luck, within the normal parameters of the relationship this person can help a lot. Utilising lecturers’ office hours is another ordinary thing that can make a big difference.
I always wonder how many of the students who feel unseen in their struggles are attending office hours and (when offered) help sessions, checking in honestly with their PTs per School conventions, etc. A common theme on this Board is students raising the alarm at home whilst telling their parents they couldn’t possibly do any of this, as it would be too embarrassing.
Eventually they appear spontaneously at the PT door in tears, and this is the behaviour we find more difficult to deal with - not least because we never have a spontaneous moment in the day. It is also arrogant to think you can bypass well thought out support mechanisms and that busy people should see you at your convenience, true emergencies excepted.
My field is sufficiently maths intensive that the same issues arise in our highly ranked School. Yes, a small amount of what students perceive as non-nurturing is a lack of encouragement. Broadly, maths-focused academics would do better to use a growth mindset with students. But more of the problem is that maths is intrinsically difficult. You need to find a way to cope, which may or may not involve leaving false pride behind and seeking help through the proper channels.
I would prioritise university choices still assigning undergraduates to Personal Tutors or Academic Advisers who are members of academic staff and I would enquire at Visiting Days what the expectations of the relationship are. It can’t be too onerous for anyone, but it’s important that both parties live up to their side. This is already a ballast for students, and makes it easier to approach the PT if necessary.
HE is hugely stressed and there is a trend to move towards providing the traditional PT benefits via Student Support Officers who are professional staff. I think this fragments the advising experience and is generally a loss.
I can easily think of equivalent hours of student orientated work SSOs could take off academics if workload is really the issue!
