Dear Pranav ,
Getting 205 is a good score but it all depends on the rank my boy !!!!
No one is gonna call you for counselling based on ya score so rank is important !!!
This is the first condition ok....
Now the second one is that you are asking for civil engg brach which is not a fancy one among students these days coz they are so very intrested in EEE,ECE & CSE ...so i guess you are in a good position to get admitted but ...old IIT's is a little hard my dear ..pray for it & you will get it for sure because last year one my pals got a score of 189 in jee got in iit-kanpur (civil engg) ..he was an obc category candidate & what a coincidence he was craving for civil engg too & he finally got it so be positive & just chill !!!
ALL THE VERY BEST FOR YOUR ADMISSION @@@
