Since your question does not gives out fact very clearly , some of the answers you have received , even though correct , are general answer.
Whether you have availed full or partial is no issue , Rules says 6 months after the date of completion of your course, repayment along with interest in form of EMI should commence. Now in your case,
Question No.1 - has your course completed ?
Q.No.2 - Why you think bank shall recall loan ? Have you defaulted in your EMI or have very large Overdues outstanding pending with the bank ?
Q.No.3 - Why you want rescheduling of loan ? Are you still unemployed after completion of the course ?
If answer is yes , whats the guarantee that you will get the secure job after sometime ? Do you have a potential offer from some company ?
If yes, you do have potential offer , then perhaps bank could consider rescheduling .
Friend, be careful , now a day Personal Credit Rating Agency have open shop in India. Even default of one EMI could spoil your credit rating & in future you will have problem getting any kind of loan. Bank wont pass on adverse report if you rescheule the loan & then maintain regular payment record as per reschedule chart .
