Well done Callum.
I passed my air law about four weeks ago, managed 87%, and I did it from the book together with the help of doing about eight practice papers.
I have a different problem to you: I am old, the last time I did any formal training or exams was 27 years ago, so my brain isn't used to learning new stuff.
The same applies to the practical stuff. When I see the young guys going up solo after barely a dozen hours it can be a bit disheartening! It took me just shy of 24 hours to go solo, and in retrospect I was pretty happy with that.
But now I am onto the met exam, and I think I will be asking for some help along the same lines as you and get an hour two of ground school to ease the process.
Congratulations again.
Cheers, Howard
