The quantity of work expected of students for both studio and investigation work is not prescribed and should be what is “reasonable” in the time available during the course. (Please refer to the “Difference between HL and SL” and “Syllabus outline” sections.) The following tables indicate the quantity of work required for inclusion in the candidate record booklet for both studio and investigation. The selection of photographs may include, where appropriate, such details as close-ups or different angles, or a series of stills.
