If your education loan has been sold to Reliance ARC and you're concerned about your CIBIL score, it's important to understand the implications of full repayment. While paying the loan in full might seem like the best option, it may not immediately resolve CIBIL issues if the loan was previously marked as defaulted. It's advisable to discuss your situation directly with the bank and Reliance ARC to clarify how the closure will affect your credit report. Consulting a senior advocate can also provide guidance on legal recourse if CIBIL norms seem unreasonable.
