All of schools in the UK the classes are paid per class. I use to do 4 times a week, but now a days I go twice a week. Karate, or any martial art, isn't a race to see how many classes one can do and how fast one can rise thru the ranks, it about perfection of character (in my opinion), if 1 class is all you can do a week, then 1 class will have to be enough. What will be the difference? Well instead of attaining your black belt in say 4 years approx, it may take you a little longer, say 6 or 8 (you get my drift). In the future things will change and hopefully then you'll be able to increase your classes. That's my opinion anyway. -ken
