I gotta say, I don’t think my time in public school when I was growing up was all that useful.

Sure, I had a few memorable classes, but for the most part, it was just filler and I couldn’t wait for the day to end.

My brother went to Catholic school and had a totally different experience than I did. Hard classes, a lot of studying, and he was pretty well prepared for college.

Twitter users shared things they believe we should have learned in school. Let’s take a look!
