Why young people find the transition between school and university challenging?

Well the experience is different for everyone,
It’s challenging for some because it will be there first time not living at home in a new environment.
Students will be going from a 30 student high school class to a 200+ lecture hall leaving the student do everything on their own with no support unless they ask.
High school gives you about 6-8 classes a day but at a university you choose how many you want but it somehow is still more than the work load which is challenging for some students to adapt too

This is highly correct because infact i just had a essay done yesterday so yeah that's pretty much what you need to do
