This text is written to match exactly the specification for teaching Advanced Biology from September 2000. Specification B is the updated version of the old NEAB syllabus. There are two student books, one for AS and one for A2. The AS book is designed to meet the level required of the Advanced Secondary qualification, the A2 book helps students tackle the greater challenges of the A2 year. The accompanying resource packs have photocopiable question sheets linked to the books. These provide extra support, practice and extension questions for homework assignments, revision, and key skill development. The resource pack content is also available on customizable CD-ROM, with artwork from the books that can be projected on OHTs.
