Otherwise no bond is legally valid now.But you are producing your certificates which is need for your future.
Think diplomatically and act accordingly.

You have signed a contract with total understanding and you need to Honour it.
Just think, if you have taken "Bond" from someone else and that persons cheats, how will you feel.
Your institute seems have selected your for post graduation with clause and its a general practice, since you are not paying for the course (thats what I can make out correct me).
They are "exploiting me" means what? Please elaborate. If they are getting work done from you, don't tell exploitation, its what they have taken you in the 1st place. You always have a choice to decline any work, if its beyond your capability. No, I am not supporting the institite, but bring the point of matter that is "Commitment to what you agreed, willfully and with total presence of mind and common sense".
You must decide Sister..... "Marriage" or "Education and work experience". As rightly mentioned by Eswar, handle diplomatically. You need to negotiate the deal with them. Marriage is a good excuse, if you decide to "consider that as your priority". Or else, you can also ask them to reduce the term..."pay them" and take the certificate and expereince cert. Remember, Institutes always supports good attitude people. Be one and be a winner in all situation. All the Best
