This accessible text will enable enthusiastic students to enter the world of secondary school mathematics competitions with confidence. This book is a sequel to the author’s A Mathematical Olympiad Primer which analysed BMO1 problems until 2010-11. Books in the Handbooks series are aimed particularly at students in secondary school who are interested in acquiring knowledge and skills that are useful for tackling problems, such as those posed in the competitions administered by the UKMT and similar organisations.
