hi there. that sounds really exciting! I understand the preemptive anxiety you’re feeling, it must be an anxious time right now.
i haven’t actually gone to uni yet, im thinking about perhaps doing a degree in the future, but I have considered some of the challenges you’ve mentioned.
I think firstly, congrats and well done for putting yourself up for this!
There are loads of ‘mature students’ out there, but you’re right in that your class will likely be mostly 19/20 year olds.
Have you considered reaching out on your Unis Facebook page, or local pages to see if any mature students would be interested in meeting up outside of classes? Others are probably feeling isolated too, so that would be my go-to idea.
In terms of your other classmates, I think the age difference does make it trickier to connect with them, especially when you’re sort of outnumbered amongst them. That being said, if I was a 20 year old in a class with a mature student, I’d just be friendly and polite and hope they would be too. I think being open to conversation, but not forcing it, is the best way to go. It’s a new experience for everyone!
A trick I think works in these situations as well is to ask a question to someone around you (something concrete like, ‘oh what was the assignment title again’). IMO it makes others more comfortable around you because you’re making yourself more vulnerable, makes interacting with them in the future easier!
Lots of love, and take it easy the first few weeks, let yourself be scared!
