A prerequisite may consist of a single course, multiple courses, or a choice of courses.
Because of space restrictions, prerequisites are written in the most concise way possible. Certain conventions have been used for consistency and clarity.
A prerequisite may consist of two or more courses (or sets of courses) that a student may chose from. Such groups begin with the word "either" and have "or" before the last choice. Separate courses (or sets of courses) are divided by commas.
Example:CHEM 237 Organic Chemistry (4)
Prerequisite: either CHEM 155, CHEM 160, or CHEM 162.
A student must take one of the following before taking CHEM 237: CHEM 155 or CHEM 160 or CHEM 162
A prerequisite choice may consist of more than one course. These groups are defined by the use of "and"".
The main division of prerequisites is the semicolon (;), which divides required courses or groups of courses.
Example:CHEM 152 General Chemistry (5)
Prerequisite: either CHEM 140 and CHEM 141, CHEM 142, or CHEM 145.
A student must take one of the following sets before taking CHEM 152:
- CHEM 140 and 141 or
- CHEM 142 or
- CHEM 145
Example:SPAN 401 The Morphological Structure of Spanish (5)
Prerequisite: SPAN 303; SPAN 323.
A student must take SPAN 303 and SPAN 323 before taking SPAN 401.
Example:CHEM 317 Inorganic Chemistry Laboratory (3)
Prerequisite: either CHEM 165 or CHEM 312; either CHEM 242 or CHEM 347.
A student must fulfill each of two prerequisites before taking CHEM 317:
- either CHEM 165 or CHEM 312, and
- either CHEM 242 or CHEM 347
A course may have a combination of groups of choices and several prerequisites.
Example:CHEM 241 Organic Chemistry Laboratory (3)
Prerequisite: either CHEM 155, CHEM 160 and CHEM 161, or CHEM 162; either CHEM 224, CHEM 238, or CHEM 336.
A student must take one of the following sets before taking CHEM 241:
- CHEM 155, or
- CHEM 160 and 161, or
- CHEM 162
As well, a student must take one of the following before taking CHEM 241: CHEM 224 or 238 or 336.
Example:ZOOL 438 Comparative Endocrinology (3)
Prerequisite: either BIOL 202 or BIOL 102 with either ZOOL 301 or ZOOL 315.
A student must take one of the following sets before taking ZOOL 438:
- BIOL 202, or
- BIOL 102 and ZOOL 301, or
- BIOL 102 and ZOOL 315
A prerequisite can include any of the following:
Additionally, the following features are available upon request:
The following are not supported by the prerequisite database and therefore cannot be included in a prerequisite:
Requesting prerequisite cancellation for your course prerequisites automatically unregisters students from a course if they have not met the specifed prerequiste. If this box is not selected, you will receive a report of students how have registered without the appropriate prerequisites and you will have to decide if the students can remain in the course.
Prerequisites should be changed only when a course's content has significantly changed.
Depending on the type of change there are two ways to change prerequisites:
