Registering for Classes

How to Register - Graduate Students

Schedule of Classes: Find Course Numbers and CRNs: 

Log in to myPurdue and click on "View the schedule of classes" to locate course numbers and CRNs. The Sr. Graduate Program Administrator will also provide PDFs with the seminar and research CRNs for each semester via email.
Selecting Your Courses: 
Students with assigned advisors: set up a meeting with your advisor/major professor to determine your course schedule. YOU and your major professor are responsible for following your Plan of Study. If you have a question about whether a course can be counted on your plan of study, please contact the Sr. Graduate Program Administrator, If you have finished your general coursework you will still register for research credits and seminar each semester, except in rare situations (see more on research and seminar credits below).
Remove Any Holds: 
Log in to myPurdue to remove holds. You can find additional information about common holds and how to take care of them here

PIN Number:

All Chemistry graduate students will use PIN Number 999999

Register via the Scheduling Assistant link in myPurdue: 

Most registrations do not require additional permission, with the exception of candidacy registrations (See the “General Registration Information” section below for additional information about candidacy registration). Requests for courses outside of Chemistry may need you to contact the instructor/departmental designee outside of the system. Here's a link to the Scheduling Assistant FAQ page.

Total Credits Needed Per Semester: 

If you are being funded by a research or teaching assistantship, you should be registered for at least 12 credits in the Spring and Fall. In the Summer, students typically register for 9 credits, however students holding internships, new students taking part in summer research opportunities or students transferring to Purdue should consult with Dr. Stephen Hoffmann to discuss how many credits of research they should register for,

Thesis Research- CHM 69900 & 69800:

If you are a PhD or MS thesis option student you are required to enroll in research (CHEM 69800 or CHEM 69900) every semester you are conducting research– even if you have met the minimum required credits for research. Deirdre Ryan will submit the list of instructors and their 69900/69800 CRNs at the beginning of each registration period. A permission will have been added to your account that will allow you to register for research credits without needing additional instructor approvals.
When you enter the CRN in Scheduling Assistant the system will default to 1 credit. You will be responsible for adjusting the credits to the desired number need to full the total credit requirement number for that semester (see point 6 for credits needed per semester). Here is a brief video on how to modify credits --

Final Check:  

Double-check your class list in myPurdue, under "Concise Student Schedule", once it is entered.
