If you read the article (or even the text in the post), it’s mostly about letting app developers test that the update doesn’t break their apps, and giving them time to fix things before the full release. Sure, some people will want to try out the new features ahead of time (and potentially report bugs to Google), but that’s only part of why they release betas.

Yeah. Probably not actually my favourite at the moment, but definitely the game I’ve sunk the most amount of hours into.

You’re undead, and use magic and guns to fight aliens and gods in defence of a big ball. The big bad is made of ghosts (but not the kind you’re friends with).

In the UK, yes (mostly). In our system, we’ve got further education (sixth form or college) which sits between high school and higher education (university). As well as providing A-level courses, colleges often provide more vocational courses that don’t necessarily lead into higher education. For example, my local college has hairdressing and bricklaying courses.

Confusingly, some universities are also made up of colleges. I think this is a minority of universities, though, and anecdotally, seems to be the older ones (Oxford, Cambridge, etc)
