its got nothing to do what you did, or your previous life, its what you can do and your perceived future ability. if its a dream of yours follow it, prepare thoroughly and fingers crossed it will become a reality.
as i remember it the only numerical reasoning is basic checking, as in matching sets of numbers in a short period of time... e.g.
167245 is on the left side of the page
167425, 167345, 167245, 176245, 167254 are on the right.
You select the exact match... think 50 q's 5 minutes to do it. varies between 4 and 8 digits
stand to be corrected if this has changed since my experience though, any other q's fire away
