Number code is the second half of the course code which consists of a number with four digits.
The first digit of the number code signifies the level for which the course is intended.
Level 1 (i.e. 1000-series) courses are introductory, foundation, basic skill type courses, or courses generally appropriate to the first year of a full-time undergraduate programme.
Level 2 (i.e. 2000-series) courses are intermediate level courses, or courses which are generally appropriate to the second year of an undergraduate programme.
Level 3 (i.e. 3000-series) and Level 4 (i.e. 4000-series) courses are those courses which involve more advanced study skills often requiring Level 1 and Level 2 prerequisites.
Level 7 (i.e. 7000-series) courses are postgraduate courses.
In general, there is no requirement that Level 1 courses be taken in the first year; however, they should not normally be attempted in the third or final year. Level 2 courses will not usually be taken in the first year but they may be taken in the third year. Level 3 and Level 4 courses will normally be taken in the third year or final year.
The second and third digits are assigned to courses in sequence number order.
The fourth digit signifies whether the course is a year or a semester course, i.e. 0 for a semester course; 1 for the first part of a year course, usually offered in the first semester; 2 for the second part of a year course, usually offered in the second semester.
