Thanks Permafrost!
Might as well ask a little more if so many of you have done the assessments..
Is it "just" quick mental arithmetic and aptitude tests on these assessments or am I right in brushing up on line equations, trigonometry and algebra?
If anyone remembers the hardest question they encountered that would be great. Seem to be more about double digit multiplication than 3x - 4y = 1 type stuff??!
