I guess you can have all three... if you can manage them all.
A couple of things:
With weapon choices you will be given a normal non magical weapon for sparring this is stating what weapon you would like (note if you pick a ranged weapon you will also get a long knife).
Another this is the first term (well technically the second but in the first the beacon wasnt strong wnough and only about 20 students were in school. Also magic has been long forgotten in this eorld so it would be very unlikely Cassies parents are life mages.
Last point is if you look at the day timetables you will see there are 6 places where the lesson says side class choice this means you can have UP TO (does mean you can have less) side courses as your choices. Sorry for not making this clear. Fix this and ill accept.
Also from your previous questions:
Yes each student has one main course and I will be rping the teachers (unless of course somebody really really really really wishes to be a teacher than ill read their app and accept or deny)
Thank You
