FiiO has some that aren’t super pricey (they run a range, their entry level stuff is usually really affordable), their amps and DACs are pretty solid in my experience so I’d totally look into one, second hand would definitely be an option there too.
It was one course (had a you fail the course if you got a sub 40% on the final) and I was able to rewrite the exam in the summer, loss of structure killed me coming from hs. Was definitely a wake up for me as well, had study groups and roommates in subsequent years which helped me (and unhealthy quantities of caffeine)
Got diagnosed with ADHD around a decade after graduating, which explained pretty much everything looking back.
A lot of companies require parking so you can pull out of a spot as a safety thing, it’s just second nature to me even though I haven’t had a job that requires it in years. It’s easier to see traffic that way, larger vehicles especially it’s just way easier to park that way. I’ll usually pull through if I can, but not always an option.
For the work I did, safety wise it was so that no hitches were sticking out into traffic (pedestrian or vehicle), being able to maintain eye contact with other drivers and pedestrians and for evacuation in case of emergency.
