There is really no point in getting a PPL unless you can enjoy the process before, during and after. Get the exams out of the way by getting stuck in as soon as possible. With a first class degree you will be capable of doing this with ease. Also make sure you you have a slush fund of a minimum of three or four lessons in case early slots come up or you need revision or remedial training. Fix any problems as soon as possible. Once you have a licence, make sure you use it wisely. Share a plane with someone and go somewhere interesting. Learn aeros, fly vintage; don't just knock an expensive hole in the sky.
