Hello Sridhar,
Since you have 427 marks, there is a very slight chance that you might be able to get into a government college.
I would recommend to make a list of NIT's you want to apply to and email them your score. There are still plenty of good colleges that you can apply for and pursue the subject of your dreams. You can check your rank using our rank Predictor. And for the further details, if you have any query you can even visit our website, where there is a detailed description which would be quite helpful for you https://engineering.careers360.com/colleges/ranking https://engineering.careers360.com/jee-main-rank-predictor?icn=jee-main-rp-landing-page&ici=prediction-section_c360-home
