Student loans

Q: Six years ago I applied and received a student loan from Iqraa Trust. At this point in time I was not aware that majority of their funds received is Interest money from financial institutions. My questions are:

1. Have I committed a sin by accepting the student loan without knowing it is interest?

2. Can I repay the loan that they gave me using Interest money?

3. Will students who know that it is Interest money but accepts it as a student loan to be repaid back be sinful?

Make maaf for asking such a question, but after doing some research I found out that their is no Aalim on their board or who is associated with them that could guide me on this issue.

I hope i will get an answer soon.
