yeps. no big deal. the diff. can be even more. rather, it's a known fact that the score in the last-practice-test is always less than the one scored afterwards in the real thingi. that's the benefit of these tests, they do make you start to think in th wrong dir., but overall they rather prepare you for the real thingi. how does that happen, i have no idea. but if you give a test 1 or 2 days before thy real thingi, atleast 30 points are added in your real thingi.
well, we'll know that soon anyways. rite.
