HL students will need to produce at least four written tasks (at least one based on parts 1 or 2, at least one based on parts 3 or 4, and at least one of task 2). Two of these are submitted for assessment. The SL written task and HL written task 1 are creative pieces of writing used to explore an aspect of the material in the course.
The different papers may have different forms of questions, or they may focus on different areas of the subject syllabus. For example, in Chemistry SL, paper 1 has multiple choice questions, paper 2 has extended response questions. Paper 3 focuses on the "Option(s)" selected by the teacher and data analysis questions.

D* then emits a photon (hν), to give the ground state of D: [1] I D* → D + hν. In theory, one photon of light should be given off for each molecule of reactant. In practice, the yield ("quantum efficiency") is often low owing to side reactions. For example, A could be luminol and B could be hydrogen peroxide. D would be 3-APA (3 ...
