I'm not a pilot, but even for the PPL I think sharing the learning experience with a group of other students is a good thing. This schooling will obviously cost, so a study group of like-minded people could be an alternative...personally I enjoy being presented with material to consider and assess rather than self-study alone with some rather dry textbooks for comapny. I know the tests aren't "difficult", but that doesn't mean the learning has to be ALARP. If you intend to process further, then it will be money well-spent IMO.
