Nelson QScience Biology Units 1 & 2 is written to support the development and application of key knowledge and skills for students studying senior science.
The student book comprehensively covers the new senior science syllabi and provides the framework for students to achieve success in one or more of the general science courses: biology, chemistry and physics.
The consistent approach used in the text promotes familiarity for students, supporting practice and revision of the content learnt in class and in preparation for assessment and exams.
