Hey,

Though the official cut-off marks of Indian Institute of Engineering Science and Technology Shibpur for this year hasn't released till now, we have to use previous year's cut-off details in this regard. You can also check it from the following websites:

So after analysing the article provided in the previous link, I guess it becomes quite clear for you that if you want to get chance in the topmost departments like Computer Science and Engineering, Information Technology, Electronics and Telecommunications, Aerospace Engineering, then you've to secure almost 15-20k rank in India in JEE MAIN 2020. But if you are happy with the bottom-listed departments of this college like Metallurgy and Materials Engineering, Mining Engineering etc then 45-50k rank in JEE MAIN would be sufficient for you. So it's completely your choice.
