why study in the first place if you don't want to do it?
A good question and one I asked myself when I was on my full-time groundschool course. Considering that we'd all paid £6000 for the privilege I was surprised how the class divided into two approximately equal halves - one half who studied their asses off and one who had no interest in learning whatsoever. The second lot were only interested in thinking about the IR they were going to do further down the line, and saw the groundschool merely as an inconvenient hurdle on the path to the airlines. Many people may consider the ATPL theory to be essentially packed full of irrelevant nonsense, but we still all have to pass it, so what's the point in complaining.
It may be worth pointing out that at least one of the people who didn't study was still trying to pass his exams two years after the first of us passed!
