IIIT Allahabad is better than MNIT Allahabad if you are interested in coding. Although NITs and IIIT Allahabad both are centrally funded technical institutes. The only difference is the course curriculum as IIIT Allahabad focuses only on IT and ECE. Due to this, minor subjects like Chemistry, Applied Mechanics, Engineering Drawing are dropped in 1st and 2nd semester itself. 

NITs have a long legacy making it more reputable with strong alumni across all domains. On the other hand, IIITA is a young institution and follows innovative academic policies. Its alumni members are even present in Silicon Valley in a short span of time.

You can decide your own priorities in the career. If you are interested in coding culture and look forward to great internships and placements with a small cozy campus, you should prefer IIIT Allahabad. You should opt for MNIT Allahabad if you are interested in meeting new people with diverse backgrounds. It will help you in enhancing your personality. 

If you ask me, my vote goes for IIIT Allahabad on all these below parameters.

• College Life: IIIT Allahabad is an institute of national importance, and boasts one of the best campuses in the country. Whereas, MNNIT is not even on the edge.
• Placements: 96% of the students got placed and received job offers from more than 120 companies. All major Computer Science companies like Google, Facebook, Amazon, and Adobe come to IIIT Allahabad's campus and make offers.

The following table shows the placement statistics of IIIT Allahabad:

IIIT Allahabad has placements in Google Mountain View/ Europe/ Australia/Japan from almost every Batch from the past 4-5 years. IIIT Allahabad was preferred by these companies because a lot of alumni already worked in these companies and better industry perception has been built up.

The strength in NIT-A is approximately twice as compared to IIIT-A. And every year this strength keeps increasing. As you know that the quality decreases with the increase in strength, I would again suggest you choose IIIT-A.

If you are an OBC aspirant and want to fetch a seat in CSE MNNIT Allahabad, you need to score above 205 marks in your JEE Mains. If you score anywhere near 170 marks or above, there is a possibility that you will get a seat in the spot round of the counseling. 

According to the recent trend, the required cutoff for OBC quota students for CSE at MNNIT Allahabad is as follows.

However, it completely depends on the basis of vacant seats available and the number of aspirants claiming for the seat.

If your main goal is to study economics, maths and statistics then opting for IPM at IIM Indore would be a very good idea. However, the fee structure is very high. INR 4,00,000 per annum for domestic students and for international students, it is INR 6,00,000.

You will also have to study subjects which you will necessarily not like such as sociology, psychology, etc.

Another drawback is that there is no degree for IPM. You will only get a certificate from IGNOU.

In the case of NIT Allahabad, it is a reputed institute for engineering. You will be able to study subjects that meet your interests. The fees are also very less. In the placement drive of 2020, the highest package offered to the students was INR 49 LPA. Some of the top recruiters were IBM, Adobe, Accenture, Tata Steel, Capgemini, etc. The average package was INR 10.28 LPA.

For the most part, it depends upon how careful you are with your budget. Commonly, local trips, note print-outs, and books take up a quarter of the expenses. Generally speaking, the major portion of expenses technically results from the food facilities you avail of.

You can avail food from the hostel mess three times per day. Typically, the food quality can range anywhere from average to bad. However, the provision of food from the hostel mess is still quite acceptable, especially if you are a vegetarian.

Having said that, you can most likely find yourself making frequent trips to several food joints situated both in and out of the campus. Apart from that, you can pay a visit to the Civil Lines about once or twice a month at a minimum as well.

The food joints and restaurants situated in Allahabad are quite affordable when compared to other mega metropolitan or metropolitan cities. Which is to say, an average of about INR. 3000 to INR. 3500 can be quite enough to pass through a month if discreetly spent.

On the flip side, if you can manage well with the food facilitated by the mess, then you can conveniently take down your expenses to about INR. 2000 per month.

Some of my friends studied at MNNIT, so I might be able to answer your question. It is suggested that you choose Mechanical at MNNIT Allahabad rather than Civil at NIT Trichy.

Your branch of choice is more important than your college preference. In terms of opportunities, Mechanical Engineering has a slight advantage over Civil Engineering

Mechanical at MNNIT Allahabad has a consistent placement record. Mechanical students receive more job offers than Civil Engineering graduates. PSUs often choose Mechanical Engineering graduates.

Finally, everything depends on your interest and choice. So think wisely and then make any decision, because this will be the building blocks of your career.
