I'm doing about 10-12 hours a week? I stay after school for 2 and a half hours because I'm physically incapable of revising at home - I do absolutely nothing! Though, I'm not overly productive in my revision sessions at school either, but it's better than nothing. It doesn't really feel like I've been revising that much and the only grade in my mock that reflected any hard work was Maths and all the rest were about the same. I work on the weekends in a cafe so it feels like I barely have any time, especially for homework. I really want to know how much other people are doing too..
