The instruction is organised so that one third of the instruction time is spent on material for free choice. The material for free choice may be dealt with in independent units or in units that also deal with parts of the core material. The instruction must be organised in a progression as regards the demands made in the subject material. 3.2 At least two units must be organised, each planned with the main goal of studying one of the perspectives of science. 3.3 Experimental work and solving problems must be continuously included in the instruction.
Experiments done by the students comprise about fifteen lessons.
Solving problems must be done partly in the lessons and partly as written homework. Of these at least twelve must be reports on experimental work. 3.5 250-300 pages are to be read, depending on the teaching material chosen. There is an oral examination with about 25 minutes allotted for preparation, including the time spent giving instructions and handing out material. Including the time spent deciding on a final mark, 2.5 candidates are to be examined per hour.
