The finals is, well, the final stretch of the year. It’s a finale, a climax, and most importantly, long and boring. Once your tests are said and done, there isn’t much you can do as you wait. However, the rules and restrictions most teachers set are quite lax in comparison to what they usually have in place for what you are and aren’t allowed to bring and do, within reason.
One good way to alleviate the boredom of finals is, of course, games. While I don’t recommend them while the test goes on, I would say it’s a good idea to bring smaller handheld consoles to keep yourself entertained without disturbing others. Now, some people have been daring enough to bring entire TVs and consoles with them, but I recommend to avoid doing so. It would be a huge disruption and pain in the neck to drag around.
More optimal choices include art and drawing tools, allowing you to seem busy and quiet. Board games are also a great choice, allowing you to play with friends, as long as the teacher enjoys loud sounds. Snacks are also highly recommended, a good way to eat something and enjoy the feeling of some food during a boring period of testing. Be sure to prioritize your finals over your experience afterwards however!
