Hii aspirant
Hope you are doing well
The information provided you is a bit vague but I will still try to give you the best solution as per my understanding
With MMM you are considering MMMUT Gorakhpur
So let me tell you that here  10% of seats will be filled through JEE Mains examination while rest 90% seats will be filled by means of college's own selection test. And there are 120 seats for each stream in this college so you can get any field as per your rank for more information
