Course List

     | Code | Title | Hours |
| --- | --- | --- |
| The following four courses are required: 1 | | 13 |
| [CS 173](https://catalog.illinois.edu/search/?P=CS%20173 "CS 173") | Discrete Structures 2 |  |
| [CS 124](https://catalog.illinois.edu/search/?P=CS%20124 "CS 124") | Introduction to Computer Science I 2 |  |
| [CS 128](https://catalog.illinois.edu/search/?P=CS%20128 "CS 128") | Introduction to Computer Science II 2 |  |
| [CS 225](https://catalog.illinois.edu/search/?P=CS%20225 "CS 225") | Data Structures 2 |  |
| Students must take two upper level courses, each from CS at the 300 level or 400 level. At the 300 level, all CS courses are allowed, except [CS 397](https://catalog.illinois.edu/search/?P=CS%20397 "CS 397") and [CS 398](https://catalog.illinois.edu/search/?P=CS%20398 "CS 398"), each of which may only be used by prior special permission from the CS Academic Office. At the 400 level, all CS courses are allowed, excluding [CS 400](https://catalog.illinois.edu/search/?P=CS%20400 "CS 400"), [CS 401](https://catalog.illinois.edu/search/?P=CS%20401 "CS 401"), [CS 402](https://catalog.illinois.edu/search/?P=CS%20402 "CS 402"), [CS 403](https://catalog.illinois.edu/search/?P=CS%20403 "CS 403"), [CS 413](https://catalog.illinois.edu/search/?P=CS%20413 "CS 413"), [CS 491](https://catalog.illinois.edu/search/?P=CS%20491 "CS 491"), [CS 492](https://catalog.illinois.edu/search/?P=CS%20492 "CS 492"), [CS 493](https://catalog.illinois.edu/search/?P=CS%20493 "CS 493"), [CS 494](https://catalog.illinois.edu/search/?P=CS%20494 "CS 494"), [CS 497](https://catalog.illinois.edu/search/?P=CS%20497 "CS 497"), and [CS 499](https://catalog.illinois.edu/search/?P=CS%20499 "CS 499"). The two upper level courses must be taken as University of Illinois credit (though one may be taken in a Study Abroad program). 3 | | 6 |

:   *Transfer equivalents of [CS 124](https://catalog.illinois.edu/search/?P=CS%20124 "CS 124"), [CS 125](https://catalog.illinois.edu/search/?P=CS%20125 "CS 125"), [CS 128](https://catalog.illinois.edu/search/?P=CS%20128 "CS 128"), [CS 173](https://catalog.illinois.edu/search/?P=CS%20173 "CS 173") and/or [CS 225](https://catalog.illinois.edu/search/?P=CS%20225 "CS 225") may satisfy these requirements – even if the number of credits for the transfer courses do not equal that for the UIUC equivalents, as long as the student completes at least 16 total credit hours for the minor.  If fulfilling the course requirements described herein does not yield 16 credits as a result of differing credits for transfer courses, then the student must take additional CS coursework that is approved by the CS Academic Office, sufficient to yield a minimum of 16 credit hours for the minor.*

Credit for these substituted courses will count toward the total credit hours for the minor.* [MATH 347](https://catalog.illinois.edu/search/?P=MATH%20347 "MATH 347")*,* [MATH 412](https://catalog.illinois.edu/search/?P=MATH%20412 "MATH 412")*, and* [MATH 413](https://catalog.illinois.edu/search/?P=MATH%20413 "MATH 413")*will not count as upper level courses for this minor.*
