Each exam currently costs £62.
As far as I'm aware, you have to be enroled with an approved training organisation before you can sit the exams. You cannot just apply off your own back, although someone might have more info on this than me.
You can do as many as you like in one sitting, however you don't have enough attempts/sittings to just do one at a time.
You have a total of 6 sittings and a max of 4 attempts at each exam.
