The length of my new program (Bachelor of Science) would only be 3 semesters (unless the duration of the first semester studying under Bachelor of Computer Info Systems counts as well), so that's why I was worried.
----------
Additional context:
I have already studied for 4 semesters (2 years) at a partner institution in India, so I just need to complete 4 more semesters (2 years) in Canada to get my degree.
The first out of those last 4 semesters (Fall 2020) is already under progress and I'm studying under Bachelor of Computer Info Systems for this semester.
I plan to transfer to Bachelor of Science starting next semester (Winter 2021) - and all of the credits that I earn during the current (Fall 2020) semester are transferrable to the Bachelor of Science program.
