Study / Poland Student Visa Query - Canada and study in Poland [3]

I Have completed bachelors in Engineering and working for 2 years with 60% aggregate in academics. I Had applied for canada student visa but got refused twice for the same intake in 2015. I had 7.5 in Ielts (expired result) . I do have 299/340 in GRE. the reason i'm worried is because in total 4 times ive been rejected without any reason at all.

The only reason I wanted to go to canada was that my gf (indian, not someone I met on fb , so No stereotypes, lol) is there from past 3 years but it all went in vain as I never got the visa anytime despite having good background. Everything I had done was perfect like funds, docs, etc. I have seen people with no command over the language go and I cant for my studies.

So, I got admission in the best university in POLAND and now i'm completely focused on my carrier.

So kindly let me know whether there will be any issue and if there might be what can I do to tackle them before they arise BECAUSE IM TIRED OF FAILING IN MY LIFE.
