1) As far as I am aware you can have up to 36 in a class, but this number would be divided into two for teaching purposes.
2) Approx one class per month starts.
3) If you have the money you will get onto a course so there's not really any over subscription. One course I heard of was delayed due to undersubscription.
For course details see

Hope this helps,
