Hi Ujwal,

As you mentioned your score 205 in JEE Mains 2019 so your rank will be nearly between 4500 - 5000 as per previous year prediction. So in order to get admission in top NIT for computer science branch the minimum rank for general category should be below 6000. You have chance to get almost all NIT's except NIT Suratkal. Don't worry you will get definitely top NIT college. NIT Suratkal, NIT Waranagal, NIT Allahabad, NIT Delhi, NIT Trichy are some top NIT's.
