Ask the lender to show what happens if you pay the accrued interest during study instead of letting it accumulate. Compare three balances at EMI start: no interest serviced, half the interest serviced, and all accrued interest serviced. This shows the real value of making voluntary payments during the course.
Also check whether disbursements occur at the beginning of each semester or in smaller tranches. Interest on ₹10 lakh disbursed over two years is very different from interest on ₹10 lakh released on day one. The timing of disbursement can matter as much as the stated rate.
Keep your own spreadsheet and reconcile it with the lender’s statement at least once during study and again before the first EMI. If the outstanding balance is materially different from your expected calculation, ask for an explanation before regular repayment begins. Catching a capitalisation or disbursement error early is easier than disputing years of interest later.
