I am from India as well:
I submitted the following:
My Bachelors Degree (Computers)
Marksheets
Letter from institute stating that medium of instruction was english
Master's degree (Computers)
Transcripts
Letter from the university stating that medium of instruction was english
These were accepted.
What you can do is get "English medium" letter from your institute/university and attach it with your application (for both bachelors and masters).
Now, remember, it depends upon case to case whether yours would be accepted or not. There must be a internal criteria by which cic can determine if the language proof submitted is acceptable or not. Maybe they check passing score and type of course/education done.... just my wild guess.
