Having completed the PILAPT test at CTC recently all I can recommended is practice, practice practice. Its not impossible. You get three attempts on each test and ideally they want to see your marks improve after each attempt. I used
https://www.pilotest.com/ to prepare and it is pretty good. There are other sites that offer similar software but they are all roughly the same. Unfortunately they aren't that cheap but if you are serious about getting into the industry you are going to have to get use to forking money out here, there and everywhere.
