Pilot Aptitude Test is a good way of developing your base knowledge before ATPL Theory/ground school, especially for subjects like Mass and Balance, Performance and maybe even Principles Of Flight (possibly others). But it's not needed. It doesn't give you too much of a head start, but more of a confidence boost.
I hadn't tried any of these online aptitude sites, but coming out of AS Level Physics was a definite help, as well as AS Psychology helping with some parts of Human Performance.
Best of luck.
