Has anybody used Quizaero? I've just had a look around their website, it looks quite interesting and easy to navigate. The price is around £60 - £80 cheaper than CATS and EasyPPL but then I think you only get 6 months access with Quizaero rather than 18 months with the others. Any thoughts on these would be much appreciated. (Unfortunately I can't use Bristol Groundschool as their package isnt compatible with Chromebooks).
