Hello Rohith, You have got a rank in KCET which is a bit on the lower side. I feel that due to this you may not get any premium branch in a premium college in Bangalore but there is a likelihood of you getting some branch in some of the colleges in Bangalore. To help you I am attaching a link that will predict which college you can get based on your ranking in KCET. https://www.shiksha.com/engineering/kcet-college-predictor
Best wishes to you.
