Does the six weeks include flying? If so, it's tight but do-able. Depends on your technical knowledge beforehand as to how quickly you pick it all up.
Why six weeks? Are you planning on going abroad to do the flying trainig? If so, you can do some exams in advance at any local flying school before you go overseas.
I wouldn't recommend just using the PPL confuser; everything you need is in either the Trevor Thom books or those by Jeremy Pratt.
