ground school
Well - if you want your PPL your going to have to make time for the theory!!!!
Obviously looking at a pile of books knocks your confidence a little, but what I did was take the 1st book off the pile (in my case air law) and read it with a highlighter during my lunch breaks etc taking the "important points". When I got home, I would then take my highlighted notes and write them into a notepad then that way they stick in your mind.
Trevor Thom's Air Law book if i remember correctly is split into 2 sections.
I looked at the contents page and said I'll do this in 2 weeks = 1 section per week then on the 3rd week do the revision and sit the exam.
This worked great in my view.
I did Air Law, Human Factors and Communications all 1st to knock off the smaller exams (content wise) Then I did Met, Technical and Flight Planning. I left Navigation to the end because its the last part of the flying syllabus so learning the theory hand in hand with the actual flying made navigation easier to learn. All the other 6 exams were passed just as I was about to do my 1st nav trip so the nav book could be read/learned in a couple of weeks in time to sit the GFT.
All the best - I am sure you'll find a way that works for you
