The training was basically to sit and read books all day, and it could be so much faster. Surprisingly there is no reliable test / quiz prep tool available online, just some free ones that contain errors.

Given this company is basically the best, they should really build their own revision / quiz tool. The most valuable part of training was a webinar which I took notes from, and turned into revision cards alongside info from the books and revised the way I know works for me. They could do this bespoke for each trainee in seconds now.
