Im not sure if i'm at liberty to discuss the ins and outs of the FEAST exam, I had to sign two disclaimers before I could actually sit the exam.
I personally found it difficult in comparison to the pencil and paper test. Was a lot longer and I felt a little vague in regards to the questions and what was required.
In regards to your question they aren't a lot of similarities in the pencil and paper exam and the computer one so if you didn't score too good in the pencil and paper it certainly doesn't mean you won't be cut out for the computer so keep your head up about that
It will be good to see how many they take on to the first interview, I can't imagine I will be one of them but it will be interesting.
