The lack of reply here probably means that there is no such thing.
As far as I have seen, most PPL students just buy the books and study from home. Some (most) also get an on-line quiz tool or similar to help them.
And any FI worth his salt will help you if you have any specific questions.
As an aside, many of the subjects become easier once you've seen their practical application - i.e. when you start doing cross country, met., nav., planning and performance, RT, etc. all comes together... (even some bits of air law seem sensible!)
So I'd say don't sweat too much on the books early on - enjoy the flying and the experience, then do the books when they will be easier.
