Depending on your subject and the amount you have picked (I think the max is 2 or 3 subjects.) If you only picked 1 subject worth 3 A levels which lasts 2 years then you most likely have 5-3 days off (including saturday and sunday). Each subject also has a second group which is only 2 (for the people with 1 subject worth 3 A levels) - 4 (people with 2 subjects worth 3 A levels) days a week however the days are extremely long (9am - 7 or 8 pm)this is only for people who can rarely have days off (full time workers). but if its 2 subjects, 1 being 2 a levels then another being 1 then you'll be at college for 5 days most likely. An example of this is I could've picked ICT Level 3 Worth 2 A levels however picking this subject would mean I have less units over that period of time but I would have to pick another subject worth 1 A level, like A Level maths or english for example. And that's the College life for you, well... for proto but I'm not too sure on the American college since your college is just like our University.
