Hi there,
do not worry to use PPL confuser - you not cheating yourself as no single question in confuser is the same like in actual CAA papers - the wording is different - even better practising in confuser is the way to learn because you have to think about the question...
btw: I have found few errors in it...
I am 30 this year, started my PPL last September with same intention like you and passed all exams without problem - true is that even I passed them few months ago I remember less than half anyway...
I started actual flying last month (8hrs so far
) and going to call CCA medical for initial appointment
btw: did you considered to attend ground school at local club - usualy its one evening a week - Andrewsfield does it for 15 quid
