Junior school
Schools in Spain start at 8:45 and a lot of students take the bus, you can not have packed lunch so you either stay for school dinners or go home. Lunch break last 3 hours in Spain so if you do stay for school dinner you have a lot of play time in the play ground.
Before you start a new year you have to go and get a list of books and buy them.
Some schools give you a voucher with 50% off the books which judging by the look on my mums face in the past can be expensive.
Senor school
Starts at 0800 and finishes at 2 or 3 but you must continue your studies at home usual until the early evening.
