In general, most state schools are open from Mondays to Fridays, mornings only, from around 8am to 1pm–2pm, although increasingly schools have lessons for older pupils in the afternoons until around 4pm. There are no canteen facilities for lunch in most state schools because the day ends before lunch and students eat at home. Lessons last roughly 45 minutes with a break of five minutes between each lesson to allow teachers to move between classes – in Germany the students tend to stay in one room for most lessons. There may be study hours allocated for homework (of which there is lots).
