Revision booklet for 2018 IAL biology specification for unit two. Booklet contains a specification checklist, a sampling of past paper questions for each topic across topic three and topic four in unit two, and a mark scheme to follow the questions. A mathematical skills checklist from the specification is included for convenience. Year 12’s have used this primarily for homework and for end of topic assessment revision. The booklet represents various questions that students can be asked in the unit one exam, but is not intended to serve as a comprehensive review of every possible question. Students are suplemented with additional past paper questions (from sites like Physics & Maths Tutor, and SaveMyExams) as a result of this.
