Paper 1

Paper 1 is made up of multiple-choice questions which test knowledge of the core and additional higher level (AHL) material for higher level (HL) students and the core only for standard level (SL) students. the questions are designed to be short, one- or two-stage problems which address objectives 1 and 2. No marks are deducted for incorrect responses. Calculators are not permitted, but students are expected to carry out simple calculations.

Paper 2

Paper 2 tests knowledge of the core and AHL material for HL students and the core only for SL students. the questions address objectives 1, 2 and 3 and the paper is divided into two sections.

In section A, there is a data-based question which will require students to analyse a given set of data. the remainder of section A is made up of short-answer questions.

In section B, students are expected to answer two questions from a choice of four at HL** or one question from a choice of three at SL. these extended response questions may involve writing a number of paragraphs, solving a substantial problem, or carrying out a substantial piece of analysis or evaluation. A calculator is required for this paper.

Paper 3

Paper 3 tests knowledge of the options and addresses objectives 1, 2 and 3. At HL, students will answer several short-answer questions and an extended response question in each of the two options studied. At SL, students answer several short-answer questions in each of the two options studied. A calculator is required for this paper. (In biology, students will also answer a data-based question in each of the two options studied.)

the assessment specifications at HL and SL are summarized on the next page.

there are some variations in external assessment requirements for design technology, arising from the design project. A double asterisk(**) indicates where these variations occur. See the design technology guide for details.

Note: Wherever possible teachers should use, and encourage students to use, the Syst�me International d'Unit�s (International System of Units­SI units)
