1) Today (Tuesday, Jan 27) is the last day to add classes and to drop classes with no tuition penalty.

2) The summer schedule is posted although it is not open yet for registration.  There is a summer course available for MS students:  STAT 672 Statistical Learning and Data Analytics.  Additional details available at:  
http://statistics.gmu.edu/courses/stat672.html
(This course is not in the current catalog; it will appear in the AY 15-16 catalog.)
The course is limited to 25 students.  So, if you are interested, I suggest that you sign up as soon as summer registration opens up, which is posted online as being March 9th.

3) If you plan on graduating this spring, you need to submit your graduation application via Patriot Web by February 20.  If you are also earning a certicate at the same time, then you need to submit a separate graduation application for the certificate.  Information about graduation is available at:
http://registrar.gmu.edu/students/graduation/

4) If you are interested in earning a certificate along with your MS degree, I suggest that you add it to your MS degree now.  You cannot graduate from a certificate program in the same semester that you add it.  The form for adding a certificate is:

As always, I am available to answer any questions you may have.
