dear student

hope you are doing great. As per your query  I would glad to tell you that at your rank you holds very low chance of getting admission into lower nits . NIT seats closes below 600 rank general rank and 300(category rank of obc). I would request you to start preparing for next attempt and work hard and mainly focus on maths as it contains lot of weightage and computer also(because it is most easy section to prepare in less time).
