Yes most people have got this reason including me. And I also got one more reason of purpose of visit.Dis any one got rejected on this note "Your proposed studies are not reasonable in light of one or more of: your qualifications, previous studies, missing marks sheets, academic record, level of establishment, language abilities, or your future prospects and plans"
As someone has said here, probably I got this reason due to duel intention they saw in my profile as I also have PR application running in the background (it’s just in pool, not even picked actually!). Although they say that duel intention is legitimate, in the end they don’t approve it.
So guys, those who have PR process going on, I would advice not to apply for a study permit,
