I have never done these for a consulting firm; I can only speak about banks and blue-chip companies.You are compared to a peer group and scores are in percentiles. i.e. for graduate roles, you'll be compared to the benchmark set by all graduates who have taken the test. If they are recruiting a chartered accountant, your peer group is all CAs, etc. Then the firm normally sets a cut-off point, meaning you will not progress past the tests if you score below a given percentile.I imagine PWC would set this at about 60/70%, depending on the role (maybe even higher for Corp Finance/ Strategy). I wasn't aware the MBBs did these tests, but if they do, I suppose they'll only take 80% and above. All this is pure speculation, I've never worked for any of the firms in question.You'll find a lot of practice tests online. And that is important, you really should practise. The tests are not difficult -lower than GMAT standard-, but they are time-pressured. I recently took these tests and scored in the 99th percentile of chartered accountants for numerical reasoning. I am no maths genius and I didn't even finish the test. I simply prepared well (5 or 6 practice tests).Good luck!
