Hello.

If we look at previous year's cutoff for Computer Science Engineering at IIT Bombay, the closing rank for General category in the last round was 66. For females (including supernumerary), the closing cutoff was 248. The cutoffs vary each year and depend on the number of students appearing for JEE (Advanced), those who qualify JEE (Advanced) etc. IIT Kharagpur will release the cutoffs for this year after the completion of JEE (Advanced) 2021. Hence, you need to at least secure a rank in the top 100 (General) to get admission into IIT Bombay.

For more information about the cutoffs, you can go to the following link: https://engineering.careers360.com/articles/jee-advanced-cutoff-for-iit-bombay

I hope this helps.
