Hi Javed.

The official cutoff of JEE Mains 2020 will be released along with the final results after the April JEE Mains. The NTA will announce category wise cutoffs then. But you can still check your estimated rank using the formula (100-your total percentile)*869010/100. So with this percentile, your estimated All India rank will be around 43,500. Now, if the candidates appearing in April's JEE Mains increase, then your rank would increase too.

Now, if you have a reserved category, you have chances of getting a seat. But if you are of the general category, you can only get NIT Patna if Bihar is your home state. You can refer to this link for detailed cutoffs for NIT Patna - https://engineering.careers360.com/articles/jee-main-cutoff-for-nit-patna?__cf_chl_jschl_tk__=ce744d9baa617488ad0aae22e87a2a2bf7118506-1580975627-0-AWuqirSsFcmqQlvZ6N3kTNV2Xy-uOggz1rzNK5cvIKF_gayktH8XE9sWxOJoojvSXXmFOsth9KP-cNTv-NePeTzuS3k-N-y_CBLTG5SpJpTANpVeXYvZ1PjmV3zkjGur44uS6rsVA4GErEZ5IIpCZeYCfOZKXDcbWWqMKOeNY2mjfKohCt6Ohb9g6-1q3IQ-I-gNAOabk37k1lwJq3IcxbL_AuI28QM9Vw7DcXTtoMrn2L3C2Gx3-hM0RT0PEo8sM2tdFTDjJVtjqkc_azbbriqIJiuepq8DaEs9f_zlKNs0tfDVHbeBlEm07RlaWpfAUw For knowing more about the colleges you can get, check out this college predictor -
