I have to decide between IIT Patna CSE AND IIT Indore CSE. How is IIT Patna rated?

When you are considering CSE at IIT Indore and IITP, the major difference that comes into play is the student activities and the groups that will help you shape your career than any faculty or curriculum. In my opinion, IIT Indore is much better as compared it IIT Patna.

You will also find a really good functional programming group at IIT Indore. It also has a number of ACM ICPC contests that are enriched into you right from your junior year. The senior-junior interaction is also pretty great considering CSE. Here is some more information regarding IIT Indore:

• Location: IIT Indore is based in the industrial capital of Madhya Pradesh. You will find a number of IT companies including those like TCS and Infosys which are building large campuses in Indore. The food here is really good too.
• CSE Department: The department at IIT Indore is excellent. It has helped students partake in many worldwide coding competitions and they have qualified thrice for the finals in ACM ICPC. This clearly proves how good the coding culture at the department is. 
• Campus: With an area of 510 acres, you will find that the campus has all the necessary infrastructure and there will be no dearth of necessities there.
• Co-curricular activities: The student gymkhana here takes care of all the co-curricular activities on campus. There are many different clubs like dance, literary, music as well as kalakriti, etc. The annual fest ‘Fluxus’ is the largest techno-cultural fest in central India. The i5 summit is also one of the largest entrepreneurship summit organized by IIM Indore and IIT Indore.

Additionally, you should also consider the opening and closing ranks at both institutes. From my knowledge, IIT Indore CSE accepts higher ranks as compared to IITP which accepts lower ranks. Clearly, the former has good rank holders, good faculty, and better coding culture. It is much more developed.
