'A' level's, I haven't got any of those, 'O' levels, I got five of those, none anywhere near to A grade. Math's was one of my worst subjects, and I'm still weak with mental arithmetic. I'm a B737 Captain now, so I don't think that your school grades are too important, as long as you've got some passes under your belt. It's down to your Commercial Pilot exams when it comes to getting your licence, and then whether you're the right type of person whether you get the all important job at the end of it all.
