Hi Norton,
I've found Air Law a real pain. However, I do have to work in my own business 7 days a week and I have a high-maintenance family with all the attendant time demands and distractions. Plus I'm no spring chicken!
So learning this particular subject (by common consent the most onerous) has been a trial for me. Don't know what your circumstances are, but they play quite a big part in how easy you'll find it to study.
Kev.
