What college can i get with a score of 753 and rank 390 in CS (General Category)
As of now its tough to say because the analysis and also cutoffs change every year due to many factors like total students appearing for exam,difficulty level of paper etc.based on previous year data you have you need minimum of 700+ to fetch seat in IIT bombay for CSE.the last year cutoff for cs general category for IIT bombay was 750.so you have few chances to fetch seat there.also you have few chances in IIT delhi,IIT kanpur.however you also have chances to fetch seat in nits.
note that as each year cutoff changes so are your chances into colleges.for more information refer to: https://engineering.careers360.com/articles/gate-cutoff
