I'm assuming it's Highland Aviation you're with. Great outfit - I did some training and my skills test with them a few years ago. Met David B at Oban a couple of weeks ago!
Pretty good advice on here - save your cash for air time, until you really need to spend on the 'extras', and stick in at the groundschool - I didn't, and took me seven years to get my PPL.
Watch out for Neil's dodgy poems - nuff said!!!
