Is it OK to exclude 'extra courses' from the GPA reported in my CV? I am a PhD student in a physical science major. I finished ALL of my required courses. Assume my current GPA is 3.5. Currently, I am taking 'extra' courses from another engineering department. Some of these courses are indirectly related to my research, but some are completely unrelated (am taking them for pure personal interests).

Now, say I got less than 3.5 in these course. My official University Transcripts will include these courses and report a GPA of less than 3.5.

However, in my CV, I plan not to do so and exclude these courses, and report 3.5, nothing less. My stand is that these were not required in the first place, and some of them are even not relevant at all. It is not fair for me to have them included.

Is there any problem with this?
If you write 


  GPA: 3.5


in your CV, this implies that your official cumulative GPA as per university records is a 3.5. So to write this is misleading, and unethical.

If you want to list your GPA only for courses in your own department, you can write


  Major GPA: 3.5


or 


  3.5 GPA in physical science courses
