Dear Ola1974, Suryak86, Scylla and others,
I did not know about this until today when I read your posts.  I stupidly worked full-time during my last semester (September-December, 2014).  I received graduation letter from my university late February 2015.  I have a valid study permit and a valid co-op work permit.  I am still working full time now for the same company and I am now thinking about applying for my PGWP.
I would very much appreciate it if you could please advise me what I could do to correct this situation due to my stupidity and honest mistake.  What is the chances of getting my PGWP?  I am really worried.  Please help.
Thank you very much in advance.
