Studying for exams
Whilst slightly off subject.....I also started flying in order to get an NPPL(M) on a Ikarus C42. However I changed to NPPL(A) and in fact wish I had spent the time and money simply getting a PPL. The reason being the studying is very similar for all the above (albeit NPPL(M) is less onerous - although I am no expert in that regard).
Whilst many people will sell you studying material or teach you to fly, people with comprehensive knowledge of the exam syllabus (and the ability to teach that well) are few and far between. Winter is a good time to study. RT is also hard but much of that is familiarity.... Good Luck !
