Maths - Fractions, number sequences, algebra, sums etc
Critical thinking - Read a paragraph and make deductions, inferences etc from it
Personality Profile - Usual stuff about Otters
Group Exercise - Always amazes me how many people don't know how to play this game.
Group Ex many not be part of Day 1 anymore. There is no real technical knowledge needed for any part of the selection process, I imagine that the company figures that since you have passed 14 exams and sat at least twice with CAAFU you already have it.
