I went to a high school where I had to pull a couple all nighters to finish a few papers too. Honestly, that’s how you know the education is worth while (as weird as that sounds). In my experience, if you’re pushed more in hs, you will have an easier time adjusting to a college level education (if you choose to go). That being said, I wouldn’t worry too much about the work you have to do in the future. You’ll cross that bridge when you get to it. Instead, just focus on having fun and being yourself for the first year. Do the school work you need to (I really doubt it’ll be all-nighter work your freshman year), have fun and make friends, for all you know they could be the best friend you ever find in your life.
