In this publication an overview of ten years of Mathematics A-lympiad is presented. Not only the 'milestone' of ten years is reason for publication; also the fact that more and more countries all over the world are interested in (joining) this competition on real world mathematics problems.
This book contains assignments of the last ten years; there is a chapter on assessment of answer papers and how A-lympiad assignments are designed is also described. Of course there is also a chapter on the 'what and why and how' of the Math A-lympiad.
