Hiya!
In addition to all the good advice and points that have been raised already, I'd just like to reassure you that it *can* be done. I don't have an official diagnosis of APD because mine is a rather complicated case (I fit all the symptoms of APD but pass all the hearing tests, as I'm a trained musician. So even though I have hearing problems, I can compensate for that well on hearing tests
). I was sent to the National Hospital for Neurology and Neurosurgery and though the consultant there couldn't/wouldn't say anything for definite, she did concede that I appear to have all the symptoms of APD.
As I didn't have an official diagnosis and these things were still under investigation throughout my undergrad degree, I never thought about getting any support for it. I muddled through my music degree (!) without any official help. It was quite challenging at times, dealing with softly-spoken lecturers or lectures in boomy halls, or people who had foreign accents (as awful as that sounds, I do really struggle understanding most people from overseas
). The main thing that was affected was my violin playing. After years of trying to struggle to tune my own violin or tune other people's violins, I've had to put my violin playing days to one side, probably permanently
Also there are some things that, even on the best speakers, I can't hear in a lecture hall. Like bass drums sometimes for example, or bass guitars
Even without having a diagnosis or official help in place, I found people were quite willing (once I explained that I wasn't being rude!) to repeat things, speak slower or more pronounced sentences, etc. I just wanted to write a little about my experiences to show you that it can be done
Since you have an official diagnosis, I imagine you'd be eligible for proper/official support from your uni, as well as DSA, as mentioned above.
Wishing you all the very best of luck. Just be honest with people about your hearing - you'll find most people are willing to make adjustments and to help (in my experience, at least)
