Hi Sam
I don't Know of an online solution to your problems but as an instructor I sympathise with your situation.
The Pooleys Helicopter P of F book does have some errors but does more good than harm when trying to come to terms with these helicopter specific exams. Don't get me wrong, but Wagtondonks book is great, a bit too involved and daunting for PPL. It has its Merits but for a non technical minded student it can be scary.
