check with your school as they may require you to do Air Law first. also it depends on how frequently you will get to take lessons. if you're going to do your lessons after a period of time it might be wise waiting till you've got a few hours under your belt before starting your exams as you've got a year in which to complete all your exams and another year in which to complete the PPL.
I know 2 years sounds ample time to do it, but if you're anything like me and have had loads of cancelled lessons due to poor weather, it's no surprising I've only clocked up 30 hours within my first 18 months
