Education loan turned npa repayment extension/reschedule

Contact the banker. Nothing is impossible.

You can write a letter proposing for rescheduling the loan to a superior officer over the Bank and take a chance.  You have to explain the reasons specifically of your inability to pay the loan and as to your proposed plan and the assets you are having.  They may consider in all genuine cases.  Even if Bankers go to court, there is no further harm to you as you can state the same thing before Lokadalat and it takes years to get a decision.  If you have offered any type of security, then Bank is having such powers of taking possession of the property offered as security.   The moment they have treated it as NPA your financial career came to an end as it is not possible for you to raise single rupee as a loan or credit from any financial institution with such CIBIL rating and branding as a defaulter.

actualy bank is not to blame if you couldnot get the salary as you expected from the course. 

The bank may not be interested in delaying legal procedure to the extent that the recovery becomes time barred. prudently they should initiate proceedings now.  You can just put before court that you are not pleading lack of limitation if the bank extends payiment schedule os that bank is cleared off the fear of limitation and is not compellled to start proceedings immediately.
