FTO assesments are garbage, all they care about is whether or not you have a cheque for around 100k in your back pocket.
You cant tell if someone has an aptitude to be a pilot or not by some ****ty computer test followed by 30 mins in a cessna. Get real, you cannot assess whether someone has an aptitude for flying or not until around 20 hours into PPL training. Which is why i always reccommend that people get a PPL first before deciding whether or not to go after a cpl/ir.
