[It's not a duplicate post]

Though both degree and diploma programs offered by Royal College of Canada have the same fee, I opted for diploma program because upon completion I can transfer or pursue a range of degree programs in universities, Canadian and international, that Royal College has transfer arrangements with. I thought that this program will give me sufficient time to think through the exact degree I want to obtain. Also as diploma programs are less onerous I will have sufficient time to get adjusted to Western academic culture and environment.
1: Is the above paragraph correct? Would you like to suggest something?
2: Does Western also apply to North American culture, particularly USA and Canada, from the point of view of a person living in Asia?
I opted for the diploma program

I thought that this - better as 'I think this' or 'I believe this' .

I will have more time to adjust to Western academic (Western is fine)
Thank you, Nona.
