That is outrageous.
For the Mountain Leader course, I have to do two more wild camping nights (which don't have to be solo)... though it's always best to do more, as it shows enthusiasm; also I have to study flora and fauna and some geology - not to become an expert, but to demonstrate some interest and knowledge. The assessment takes place over five days at the end of April, but my qualification will be deferred until I get my First Aid certificate, which is booked for the end of May.
It is quite demanding, but I suppose anything that allows you to take on a new career is demanding.
