What does a typical A-Level timetable consist of?

my normal lesson (a session/cl we have them in blocks) are about 1 hour long but i also have some doubles an some hour and a halves. i have about 5 blocks a day... eg in every A block i have maths in every B block i have a free... we have 7 blocks altogether. on average i have 4 lessons per day and there are about 5 blocks a day i have four lessons of every subject a week which evens out to just under 5 hours of each lesson a week. but this all changes for which college you go.
