This page is a guide for how to use and interpret Course Network documents from ANT.

Each node in the network represents an individual course offered at the school, as well as placement exams and outside standardized tests (SAT, ACT, AP, etc.). Each line represents some kind of connection between the classes, such as prerequisite, corequisite, or equivalency.

Lines and Connections

Each line and arrow style has its own meaning. Some are unidirectional, while others are bidirectional. Unidirectional lines always have an initial and terminal course, with the direction pointing from initial to terminal. Bidirectional lines have no direction, though they might still have arrows on both ends.

Lines which represent prerequisites between courses have a normal weight and an arrow connecting the prerequisite to the postrequisite. Lines which represent corequisites look like pipes; they might also be either unidirectional or bidirectional.

Lines which share the same weight (i.e. thickness) have the same meaning. Prerequisites which share the same “terminus style” (end arrow style) fulfill the same requirement for that class. Consider the following example:

Notice that two of the four prerequisite courses share the same terminus style — a simple arrow — while the remaining two have different styles. This is interpreted as the following:
STATS 120A prerequisites = MATH 2A and MATH 2B and (MATH 2D or MATH 4)

There are many different styles that can be used. The table below lists some of the more common ones used.

Line StyleDescription
Initial course is a prerequisite for terminal course.
Courses are mutually corequisite.
Any pipe-like connection with arrows on both sides also represent mutual corequisite courses.
Initial course is a corequisite for terminal course, but not the reverse.
Initial course is a recommended but not required corequisite for terminal course.
Courses are equivalent.
Initial course can be applied as a prerequisite for terminal course since it is equivalent to an explicitly-stated prerequisite.
Credit by Equivalency. Generally only used for courses which are not offered by the college directly but are included in an articulation agreement.
Credit by Examination. Placement from initial course to terminal course is possible. May included a condition, such as minimum score.

Conditional Statements

Sometimes, the requirements for a course cannot be expressed in simple terms (that is, following only the rules stated above). In these cases, a diamond-shaped conditional statement block is added between the initial and terminal courses. All the rules of connections apply to conditional statements.

Some common statements include:

  • Same prerequisites – added to reduce the number of lines between courses.
  • Grouped options – used to show when a course has multiple sets of courses as a prerequisites, such as PSYCH 112A.
  • Mutually corequisite – courses may have more than one other course as a corequisite; in these cases, those courses are connected via a corequisite line.
  • # from these prerequisites – courses which require picking more than one course from a list of courses are connected to this block via a prerequisite line; any course connected to this block is a valid prerequisite for the course.

Colors and Subjects

The color of a course is the subject it is a part of. For example, the box representing CHEM 1A is colored purple, since all CHEM courses have that color. Below is a table of which subjects at UCI are represented by which color.
