Permitted subject combinations The grid below shows the possible combinations of subjects for TSM. Students select two subjects. Usually both subjects are studied for three years and one subject only is studied in the fourth and final year (there are some exceptions, see below). The absence of a letter or number from a grid position in the table below means that the corresponding combination of subjects is not permitted. 1 When mathematics is studied with other subjects according to pattern B it can be studied for three years only; the other subject must be continued in the fourth year. 2 Greek and Latin can be studied together only in the context of the single honor course in Classics (TR021). 3 May be studied under pattern A or B combination. A = both subjects are studied for four years B = both subjects are studied for only three years and only one subject in the fourth year.
