This book is written with the following aims:

• To recapitulate essential yet often forgotten 'O' Level Mathematics knowledge that will still feature prominently in the 'A' Level Mathematics syllabus.

• To offer innovative perspectives as far as using the GC to (both effectively and efficiently) solve problems under time constraints is concerned, as well as to advise on identifying careless mistakes whilst checking answers.

• To summarise critical concepts arising in each chapter, in addition serve as a comprehensive exam revision guide that covers useful topics not taught under the current syllabus, such as the cover-up rule, sum/roots of a polynomial (involving orders higher than 2), L’Hôpital’s Rule, shell method (for computing volume of a solid of revolution), Riemann Sums and De Morgan’s Laws.
