My gate score is 444 and SC category.I'm from civil engineering.Which IITs should I apply for?My rank is 11272.

Your rank and score is a bit good.You have very thin chance of getting to the Old IITs such as IIT Bombay, IIT Delhi, IIT Kharagpur, IIT Varanasi,etc.You may apply for this colleges and let's hope you will get it ,but as a backup you should also apply for other new IITs such as IIT Ropar,IIT Mandi, IIT Guwahati, IIT Patna and other good Private colleges too.
Be hopefull.
