BIOZONE continues the innovative development of its highly popular student resource for IB Diploma Biology. Our new edition is a significant upgrade to our previous edition, now being in full colour, 600+ pages in extent and now a true worktext resource - combining the very best features of a highly visual textbook (using an infographic style) with the utility of a workbook. Specifically written for the latest IB Biology Diploma program (first assessed in 2025), this resource integrates BOTH standard level (SL) and higher level (HL) material, ensuring seamless delivery of the IB program with no content gaps.
