The remainder of course fees are due before the course starts as normal.
Maybe I should have made it more clear. When I mention “remainder” that is the amount that remains after the £1000 credit has been taken. So, as ROG said, if the course is eg £1200, there is £1000 credit with the remainder being the deposit of £200 which is due before the course starts.
There really is no catch, no smoke, no mirrors.
