Suffice to say there are many places (already mentioned) on most campuses where you can find solitude. The one that immediately comes to mind to me is just sitting under a shade tree for a half hour or hour (or whatever) on a nice day. If that’s not available, most student centers have “lounges” with sofas and general spaces.
When visiting S on campus, I’ve noticed that many kids opt to study in random rooms around campus. Most have laptops out and headphones on. Easy to find these spaces. You may need to seek those out as the dorm and dorm room may not be that private.
