With the score you're mentioning you'll get a rank somewhere between 1-270. If you fall in general category and have the state domicile of either Chattisgarh or Punjab then you definitely have a chance in both the colleges. Even if you don't have the state domicile you can easily get into those colleges. The cutoff is decided as per how many students are scoring more. So you don't have to worry as you have a great score so even if it's higher you can easily get it as the closing ranks for HNLU and RGNUL are 750 and 980 respectively.
