High school and college are completely different things, obviously. There is generally much more studying in college in order to succeed. High school does not require nearly the amount of effort to get through. In high school, there are several three day weekends here and there for things like parent-teacher conferences and holidays like Columbus Day - days that colleges do not close for and classes go on. With that being said, colleges generally give more time off for Thanksgiving and Christmas and sometimes even Spring Break. High schools give two weeks on average for Christmas break and usually for Thanksgiving its just a 4 or 5 day long weekend- not a whole week.
So the first break college students get is the three-day weekend for Labor Day. High schools give that off as well. However, between Labor Day(beginning of September) to Thanksgiving(end of November), there are no breaks for students in college. Like I said earlier, high school students get three day weekends and stuff like that for the smaller holidays(Columbus Day, Veteran's Day) and parent teacher conferences between Labor Day and Thanksgiving Break.
As a first year college student, I can speak on behalf of all other first, second, third, etc. year college students when I say that two and a half months of school with no breaks is exhausting and very difficult, especially when coming from high school where breaks are common. After midterms (mid-October), college students are ready for a break and ready to have at least a three or four day long weekend for a break.
The problem with not having a fall break in college is that by time Thanksgiving comes around, college students are worn out, tired, and have lost almost all motivation. With no break, by the beginning of November, college students start struggling because of the tedious five day weeks and homework assignments. It would be better for the mental health of college students to take a break from thinking.
December and October should be similar for college students; December is finals week and then Christmas break. October should be midterms and then a "fall break" for college students.
