Answer 1

Answer:

every school has different timetable....

Answer 2

High school timetables are quite different from university timetables. The main difference is that in high schools, students have to be occupied and supervised every hour of the school day, or nearly every hour. Also, high school teachers generally have much higher teaching loads than is the case in universities. As a result, it is generally considered that university timetables involve more human judgement whereas high school timetabling is a more computationally intensive task, see constraint satisfaction problem[1].

Block: This term is ambiguous, but in this article it refers to a set of lessons of different courses that must be placed concurrently.
Student body: A set of students who are timetabled together, for example the 8A roll-call group.
Band (or cluster): A set of classes involving the same student body, which are therefore horizontally linked, meaning they must be on separate periods.
