Hey! I have ADHD (quite severely) and pre-clinicals were AWFUL. Honestly, I crammed for every single exam and struggled through by pure luck I think.
My main two recommendations are:
get whatever accommodations you think you could possibly need through your student disabilities office. I found it reassuring to at least have it formally documented even though I NEVER used mine (my school actually rejected mine... during covid I was denied the ability to use scratch paper on virtual exams, despite it being a very specifically reported accommodation, because it would be "inconvenient" to proctor my exam individually instead of with the automated software, but that's another issue). The other one is investigate medication. I have horrible medication compliance and forget to take mine more often than I take it, (the inconsistent schedule of clinics is a nightmare for my adhd), but I started to take medication during the last year of preclinicals and it was literally life changing to be able to just sit down and study rather than my eyes glazing over paragraphs for hours.
Vet school sucks for everyone, and sucks doubly for neurotypical people, but you can do it. I've actually done much better mentally and emotionally in clinics, even though I was REALLY worried about my ability to "keep up" mentally with patient care. Perhaps my constant anxiety and over-cautious approach to all of my patients is not healthy, but whatever. I can sleep at night (except for my chronic insomnia)
Sorry, just saw you already have accommodations- ignore that!
I did just remember some other advice: I did not attend class, I watched the recorded lectures at 2x speed and used the lectures to identify what "key points" the professor was focusing on, and then used those to direct my studying of the printed notes. I found that I just cannot absorb lecture material, and skimming/highlighting printed notes was FAR more beneficial. There was a marked difference in my grade between the exams where the professors provided notes and those that did not. The notes made it easier for me to "organize" what I was learning, because one of the biggest issues for me was figuring out what to focus on or spend my time studying- I'd get bogged down on one topic that wasn't important. Test taking in vet school is literally a numbers game- study the things that are likely to be most of the exam and then ignore the rest. You CANT learn everything- if there's one particular nerve/ structure/etc. that you
just can't remember... give up and move on. Don't waste time on that one thing that never seems to stick- study everything else and come back if you have time. Pre-clinicals are just survival, don't worry about how you won't retain anything, no one else does.
