Computer Science Placement

This page contains information about placement for computer science courses. For incoming students who have some previous computer science coursework, this page contains information about placing into the appropriate first CS course at ISU.

For transfer students, evaluating transfer credit is separate from the placement process. Transfer credit is given based on the syllabus and course description of the course taken elsewhere, and this transfer credit can satisfy prerequisites to allow you to register for later CS courses. You still need to take the CS placement so that we know if you are really ready for the later courses; if not, then you will have some catching up to do and should talk with your advisor to plan how to do this.

Course Prerequisite Knowledge/Skills

CS 101 Fundamentals of Computing

This course has no prerequisites. The main goals are to (a) give students practical understanding of computing to become well-informed citizens and professionals in the computing age, (b) have students become familiar with using the Linux operating system, installing and using a programming language, and beginning to program in Python.

CS 151 Introduction to Computer Science

This course does not currently have a listed prerequisite. However, CS 151 is a programming course that requires you to be able to hit the ground running (do assigned reading on your own time, comprehend the reading, get things working on your computer, etc.), so we have a placement test to complete to verify whether you should start in CS 151. Those with no previous computing experience should normally start in CS 101.

Prerequisite skills and knowledge to be ready for CS 151 -

• Ability to use the Linux operating system (in particular using the shell/terminal)
• Able to install and use a programming language
• Able to troubleshoot and learn some aspects of programming on one's own using online resources

Note that CS 101 is required in the information science concentration of the Computer Science major, but is not required for the other concentrations. Those taking the information science concentration need to take CS 101 regardless of previous experience; for you the decision is whether to take only CS 101 during your first semester or to take both CS 101 and CS 151 during your first semester. CS 151 is a prerequisite for other CS courses, so if you are truly ready for it then it would be good to take. If you truly are 'not' ready for CS 151, then trying to take it when you are not ready will not help you in the end. Take the placement test, and then we will know.

The placement test is a series of readings and quizzes in one of ISU's course management systems. Those registered for either CS 101 or CS 151 will be added to the "CS Advising" course that contains the placement test. Once you are able to login to the CS Advising course, follow the instructions under "CS 151 Intro to CS - placement test". Note that this will take some time, so please get started soon.

CS 201 Programming Structures

The prerequisite for CS 201 is a C or better in CS 151. The following are the most important prerequisite skills and knowledge gained in CS 151 -

• CS 151 prerequisite skills/knowledge (see above)
• Competent programmer in Python, including use of modules and appropriate use of Python containers (lists, dictionaries, tuples)
• Competent user of your own computer (installing programs, etc.) and the linux terminal

Note that Python is a prerequisite for this course, so transfer students with credit for CS 151 but without experience in Python need to work independently to get up to speed with Python before the term starts.

For transfer students who have transfer credit for CS 151, you will be able to register for CS 201. To determine whether you are really ready, we also have a placement test for CS 201. This is contained within the "CS Advising" site mentioned above for CS 151. New transfer students should take the placement test to make sure you are ready for the courses you are signing up for.

CS 202 Data Structures and Algorithms

CS 500 Programming Fundamentals

Prerequisite skills and knowledge -

• Competent programmer in some programming language
