DS will be travelling to Uni (either Bridge of Allan or Stirling station to Glasgow) from sept. Just trying to work out the most economical way to do this. Young Person's Rail card? Season ticket? Also just seen that he can get a discount with a Young Scot card until he is 19 too. Some fares need to be a minimum price in order to get the discount. 
No idea what times he will need to travel and if it will be every day but I'm assuming at the moment that he'll need to be there for 9am but possibly travelling back before 5pm and that he'll need to go most days .
Anyone a bit more compus mentus than me that knows how it all works?
