Cheers Mazzy! I just did a quick search of the Google play store and you can get the app there - it's £9.99 but well worth it in my opinion. A lot of the questions were either very similar or near identical to those on the tests. It would probably be possible to just 'remember the answers' but I made sure I read both books fully so I actually knew the content.
Got another lesson tomorrow myself. Had my medical yesterday and there was some issue regarding medication - need my GP to give the AME a report. Hopefully it isn't going to take too long to sort as I'm just about ready for solo circuits, minus the medical certificate
