Thanks for clarifying things CJB. We all make mistakes and the wisest people admit to theirs - thus indicating further their wisdom!!
PantTwizzler, I'm very sorry to hear about your DS. Now he's going to let everyone know about his dyslexia, this should initiate more understanding and hopefully concessions with his supervisors. They should be motivated to make things work better for him because they selected him and know his potential.
Can he ask for time extensions to completing work and watching lectures? If he has a report about his dyslexia, then this ought to be possible. Can he talk to his DOS or tutor and get some support and reassurance that lots of students feel similarly to him and he shouldn't doubt himself.
His degree subject is notoriously intense and you'd expect that most students would start off feeling overwhelmed and then gradually, across 3 to 4 years, settle into things better. I really hope he can hear from second and third years that this is entirely normal and not to worry.
Right now has got to be the hardest time - midterm, of the second term of the first year, with the additional challenges of the pandemic. Don't let him judge the entire degree on how he feels right now. He needs to hear all of this from his mentors and peers however and I hope he gets their input soon.
If it helps, I absolutely hated the second term of my first year of a different degree - and almost swopped course or dropped out at that point but instead, decided to carry on. Fast forward 40 years and I now feel indebted to my degree course and tutor (this was at O) for pushing me so hard and believing in me.
Your DS also needs to get some positive feedback from his DOS/tutor so he too can see that he's more than capable. He probably just needs to take a bit of a breather and some days off - if this is at all possible.
