With a CRL rank of 347,728 in JEE Mains, it will be very difficult to secure a Computer Science (CS) seat in top colleges in Mumbai, as these institutes typically have very high cut-offs for CS. However, you might still have a chance in some private or lesser-known engineering colleges with lower cut-offs. Colleges like Ajeenkya DY Patil University, Dr. D.Y. Patil College of Engineering, and Thakur College of Engineering could be potential options. Checking the specific cut-offs and using a college predictor tool will help you get a clearer idea.

With a CRL rank of 347728 in JEE Mains, securing a Computer Science (CS) seat in a well-regarded NIT in Mumbai is highly improbable. The cutoff ranks for CS in the National Institutes of Technology, especially in metropolitan cities like Mumbai, are typically within the top few thousand ranks.

However, your JEE Main rank can still open doors to other engineering colleges in Mumbai that accept JEE Main scores for admission. While these might not be NITs, some private engineering colleges in Mumbai offer Computer Science programs.

To find potential colleges, you should explore the previous year's cutoff ranks for various engineering colleges in Mumbai that accept JEE Main scores. Websites like Careers360 can provide lists of such colleges and their cutoff information. You can filter these lists by location (Mumbai) and the Computer Science branch.

Keep in mind that with your rank, you might need to consider colleges that have lower cutoff ranks for their CS programs. It would also be beneficial to research the specific admission criteria and processes of these private colleges, as they might have additional requirements or conduct their own counseling rounds. You can also consider other branches of engineering that might have lower closing ranks if you are open to exploring different fields. Use college predictor tools available on the Careers360 by inputting your rank to get a list of potential colleges and branches you might be eligible for in Mumbai.
