A friend of mine in college pirated a japanese show which included the ads. The first episode seemed to have subs with legitimate translations. The rest of the season the subtitle author had fun and changed them to make fun of the ads. It was pretty funny.

There were no quizzes though...

I was wondering how I should prepare for the tests

As a person who uses stremio; not only is it not more of a hassle than streaming services, it's WAY less. Astronomically so. You set it up once and you have literally everything

It’s not a hassle at all. I use my phone to tell my computer what I’m interested in watching. It automatically downloads that, and when I’m ready to watch something it streams to my TV. After I’m done with it, my computer removes it.

Kodi, Seren add-on and a debrid provider like Premiumize gets me better service than any streaming provider. Multiple source streams on any show in the last couple decades and every movie way earlier than is available from any source I've ever seen. If its not available as a cached stream, I can queue a torrent file at their end and stack them up until I'm ready to watch it, but I've rarely had to do that.

Only upfront effort. Downloading is almost as much of a hassle as choosing what to play tonight.
Once it's on the disk it's fair game.
