A few observations from someone who was a real dickhead at uni and for whom this is familiar...This is a tale 20 years old, but some things may ring true...
1. You have to work hard...incredibly hard...to get kicked out of Uni, especially in your first year. Especially squared if its fee paying and you are in good financial standing (i.e. no missed payments). Especially cubed for the oft heard stoty of "im a bit tardy with commitment in my first year adjusting to adulting away from home for the first time". First year (IME, maths so ymmv) is aligning the various a-level syllabuses to ensure everyone is equally prepped (and understand further ed disciplines like academic writing and logistics) for the real learning in years 2 and 3.
2. Calls for all paperwork/comns mentioned here are a bit of a misnomer.. Between the various dept pigeonholes, campus accommodation postboxes, personal email, student email... I would have zero paper trail. They were just 4 things I had to dodge. To think of a student that was fully on top of comms, but just couldn't execute on the deliverables, is incredibly rare.
3. I retook y1 with the most committed outlook that I would return to being the most disciplined student evah...Turns out that lasted 3-4 weeks...I had the same distractions, same as-then-undiagnosed boredom with the subject matter, plus a bunch of new clasates I couldn't bond with, as if would highlight my moronic dropping of a year, and they just weren't my pals from last year (that were now a year ahead of me). I do t think I'll ever be able to be convinced that retaking y1 works in the end, I'd love to see the stats on it.
4. NGL it really hindered my job interviews (and general self worth) for my whole 20's, until the wasted 2.5 year period dropped off the bottom of my cv. In fact it was a bit of a cloud over me internally until...
5. 20 years later I got a masters from Birkbeck. Lots of people do similar (struggle with uni first time round). I was shaking when I got the result. Sad to say the first people I called was M&D, to close a bleak chapter with a triumph
