Greetings!

For, a seat in B.Tech Computer Science and Engineering from IET Lucknow, you need a rank around 488 for the category General armed force, Your rank is quiet close but it's a bit low, but I'll suggest you to wait till the final counselling as the number fluctuate every year, you may stand a chance to get into your desired college. All the best !

I hope you find this helpful. Thank you!
