# Collins CSEC® Mathematics

Collins CSEC(R) Mathematics provides a new approach to the study of the CSEC(R) mathematics syllabus. Fully grounded in the practical application of maths in the world today, it features clear explanations, differentiated practice exercises and guidance on the School Based Assessment.Collins CSEC(R) Mathematics has been written for the CXC(R) syllabus effective for examinations from May-June 2018. It provides full coverage of this syllabus, with real-world and everyday contexts for all topics to help Caribbean students understand why maths is so important for the world today, with guidance on the School Based Assessment, worked examples, and differentiated - or graded - practice questions to help students understand the level they are working at and the level they need to be working at to achieve a good grade. Written by a highly experienced teacher in the Caribbean.
