Minimum rank to get admission in IIT kanpur and IIT bhu, branch don't matter, category general
Hope you are doing well!
Now let's go through your question.
As you will be knowing that if you will clear the cutoff specified by IIT Kanpur/BHU shall be considered for the admission process. But remember that not all the candidates who clear the cutoff may get admission in IIT Kanpur courses.
And the final selection of the candidates shall be based on the components specified the institute.
Moreover, for some courses, IIT Kanpur/BHU may conduct a separate written test and interview to select the aspirants.
The minimum rank you have to secure to get IIT-K is somewhere around 8k-10k & for IIT-BHU is 9k-13k(approx) in JEE Advance.
Thank You & All the best!
