They requested for one calculator and 1 coloured passport, i thinks that is what is only needed, most of these org request for only what they need , do not be suprised if the test is data based.
but to be on a safer side go with all yah partykulars.i am going for the test in Abuja too. you can give a call on 08135881765 so we can exchange our views on what we have read so far.
cheers and goodluck.
