I give u in point, and u will generate that idea yaa, -can Foster family bond,means, that are always interaction between u and your both parents or your sibling/s - when u stay at home, u will have a lot of time to do revision - no schedule, no pressure for u, .. some people don't prefer to stay at hostel as they need to follow the schedule/hostel rule, so the become bored and that will do their work very not well .. does it make sense? ☺✨✨
