Can anyone tell that if one has one year work permit after completing one year course , is he/she eligible for PR ?
It would really depend on a lot of other factors - your education, number of years of foreign work experience, NOC, age, language score, which province you live in, etc. You should do your own research on what different paths there are to get a PR.
If you live in ON, I'd recommend starting with OINP - Human Capital Stream, CEC, FSW.
That being said, I think this thread is mostly to keep track of the PGWP timeline, so you might wanna ask further questions in another thread.
