A quick note on accuracy
These are the widely-used SSLC bands, and the calculator applies them to your entered marks. Grade boundaries for language subjects can differ slightly in some years, and only your official TN board marksheet is authoritative — treat this as an estimate for planning, not a replacement for the result.
