Yes, scoring well in your 12th boards genuinely pays off at Rayat Bahra University. Students in the 85-89% range can get a solid 50% waiver on their tuition fees, and this goes up even further to 75% for those scoring 90% and above. Even a moderate score between 65-74% still earns a 20% waiver, so t
