The university keeps the door open for many students, with the general B.Tech eligibility starting at 45% to 50% in 10+2. Specialized CSE programs such as Data Science, Cyber Security, and AI and ML ask for 60% in 10+2 with Physics and Mathematics. So whether you are an average scorer or a topper, t

Good news, you don't have to pick just one route, Rayat Bahra University lets you qualify through either your board marks or your entrance exam score, whichever works better for you. So if your 12th percentage is strong, that counts, but if you've also given an exam like JEE, NATA, CAT, or CLAT, tha

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

There is no single best one. SC students should apply for the post matric SC scheme, ST students for the ST scheme, and OBC, EBC or DNT students for PM-YASASVI, along with their state scheme.
