Hello, Saisay,
i submitted my application on the 24th of June and was automatically replied to with a link to begin my online assessment. I did it immediately (it was a literacy and numeracy test) and received a reply within half an hour with another link to proceed with the online assessment. I did this the following day, the 25th, which was a graphic and diagram reading assessment as well as some logical/rule following tests. Two days later i received the confirmation i had passed Stage 1 and should choose the day of my Stage 2 assessment in Fareham. I picked the 18th of July.
I now have approximately two weeks to study for the ATC Knowledge Test and am wondering whether and how i should prepare for the FEAST and DART tests.
I hope this was useful.
