My brother attended MNNIT Allahabad, so I can give you a brief idea about the BTech first-year syllabus at the institute. 

There are some rules followed by the institute. First groups are made and each group has sub-groups like X group has subgroups of X1 and X2. One group studies one category of the subject in their 1st semester and in the next semester they study the other category of the subject. Some subjects are common while some are different.

Common Subjects - Mathematics and Physics

1st Category-

• Engineering Mechanics
• Mechanical Engineering Workshop
• English

To get a subject-specific syllabus visit the official website. Knowing the syllabus beforehand will give you a headstart.

There are a number of scholarship programs available for you at MNNIT Allahabad. Check out the following and their details below.

• NSP (National Scholarship): This scholarship is provided by the govt. of India. You can fill the form online at their official website and then get it verified at Dean Student Welfare. This is open to all students and you can easily apply in the first year itself and it gets renewed every year.
• State Scholarships: Many state governments provide scholarships to students pursuing any technical course like B tech. It all depends on which state you belong to. The scholarship by UP govt. is the most popular one at MNNIT. Besides MP, Rajasthan is also an example. State scholarship for students from Bihar is available online on the NSP portal.
• Student welfare of MNNIT provides scholarships to meritorious students each year. You don’t need to surpass any income level to avail this scholarship. It is given to the top 10% of students of each branch considering their CPI. For first years or fresher's, JEE main rank is the criteria. For this, you are supposed to have a general rank <4000 or around.
• Student Welfare of MNNIT also provides scholarships if you do not possess good financial conditions. To avail of this scholarship, you need to prove with an income certificate stating less than a lakh per year. You should also have a CPI greater than 7.5. This scholarship amounts to about 20,000 rupees.
• Students from JNVs have special scholarships for them. ‘Samsung' provides scholarships, especially for Navodayans.
• CSS or Central Sector Scholarship is provided to SC/ST students.
• ‘Schneider Electric' provides scholarships to 2nd-year students of Electrical Engg and ECE. You need to provide an income certificate of less than 2 lakh. This one is based on your application form and online interview followed by a telephone interview.

Please mind that you need to fulfill certain eligibility criteria to apply for these scholarships which are mentioned in detail on their official websites. Also, note that you can apply for only one scholarship, not more than that. So, check which one of these is the most suitable for you and apply for that only.

My brother has completed his M.Tech from MNNIT Allahabad and according to his experience, this institute lives up to the expectations in terms of placement. Here’s why:

• If you have done enough justice to your studies during these 2 years of M.Tech, then the rest is assured. Although no specific CTC can be guaranteed, you will ultimately land a good job.
• No doubt MNNIT Allahabad’s placement cell is very active and works hard for your better future. Thus, a long list of companies usually visits for campus recruitment every year offering a plethora of opportunities.
• In my brother’s placement time, companies like Walmart, Sony, Cap Gemini, TCS, Samsung, Amazon, Directi, etc companies came for recruitment. However, you must be efficient at coding to grab decent packages in such big companies. Here also, MNNIT help you out with their bunch of bonafide students that take the "ComputerClub" classes.

Overall, if a placement is your goal, you are at the right place. Luckily if you belong to the CS branch in MNNIT or any other college in India, you can have one of the best placement packages. Most of the students of the CS branch get placed for jobs and internships too.

One of my friends was in the same situation at the time of his counseling. He had this doubt and I am sure many of the people would have it too. I will note down the pros and cons of these two colleges so you can take an unambiguous decision.

IIIT Allahabad:

Pros:

• IIIT Allahabad has a huge campus and it’s beautiful over there. In terms of campus, IIIT Allahabad is definitely better than MNNIT Allahabad. 
• IIIT Allahabad is known for its coding culture.
• You will not be taught anything unnecessary like teaching engineering drawing to a CS student.

Cons:

• The faculty base is not that great. Sometimes even seniors take the classes. 
• The timetable along with the assignments becomes very hectic at times.
• It is also a new institute. 

MNNIT:

Pros:

• MNNIT is a very old college and has a rich alumni base.
• The placements are amazing if you are persistent with your hard work and studies.
• The faculties are good apart from a few. 

Cons:

• The campus is small as compared to IIIT Allahabad also; the sports facilities are also just not that good.
• If you are looking for a good coding culture then it's here too but far less than IIIT Allahabad.
• You will need to study some subjects no matter which branch you belong to in the first year.

The table below gives a brief overview of the two institutes.

So this pretty much sums up these colleges. The final decision is yours, compare and choose wisely. 

A semester-wise view of the syllabus is discussed below. 

Semester-1: 

This is the general semester, where you have to study subjects like Physics, Chemistry, Engineering Drawing, Computer Programming language, etc along with labs and tutorials.

Semester-2:

In this semester you study advanced versions of subjects like Physics, Maths, Chemistry, Ecology, etc along with labs and tutorials.

Semester-3:

• By the 3rd semester, you get into the department and then you get to study your branch-related subjects.
• In this semester the courses are Data Structures, Discrete Mathematics, Electronics Signal Processing, and other IT-related subjects.

Semester-4: 

• As the 3rd and 4th semesters are crucial, you are taught major stream subjects in-depth such as Algorithms, Graphs and Combinatorics, Automata Theory and Computer Organization, etc.
• There will be labs and tutorials related to the courses in the 4th semester.

Semester-5:

Here you learn important courses like Operating Systems, Computer Networking, Cryptography, and Object-oriented modeling, and computer graphics.

Semester-6:

• In this semester courses such as, Database management, scientific computing, multimedia technology, Software engineering, etc are provided to the students.
• Also by the end of the 6th sem, you are allotted the mini-project.

Semester-7: 

• In this Sem, you get to opt for electives.1 open elective and 1 professional elective choice. And other subjects like Digital Image processing, Professional Ethics, Service-oriented software Engg are taught.
• These subjects are very easy and quite scoring. But you will need to work a lot on the project. 

Semester-8:

• In this semester, the department offers 1 open elective and 2 professional electives
• Apart from these, the courses are Privacy-preserving Data publishing, Research Trends in IT.

You should start coding and learning the basics of programming languages on your own. This will help you get prepared for internships.

During your years in MNNIT, I would advise you to maintain good pointers and pay attention to coding and competitive programming. Score well in subjects and try to focus more on highlighted courses because companies ask questions from those courses. Also, make good projects.

First of all, let us consider the placement. Comparison of data of placement 2017, 2018, 2019, and 2020 for the branch CSE at MNNIT Allahabad. 

Looking carefully at the above data, we observe that the number of job offers made is higher than the number of eligible candidates. The average CTC also follows a positive trend. Thus, based on placement, it is advisable to join CSE at MNNIT Allahabad.

Check the following positive aspects of MNNIT Allahabad:

• Competitive Environment: The students are selected based on their rank in JEE Mains, which is difficult to clear and the large number of students appearing every year adds to the difficulty level. This ensures a good competitive environment and nothing can be more advantageous towards contributing to better career growth than a healthier competitive environment in the college.
• Faculty: The faculty at MNNIT Allahabad is very motivating and is always ready to help you in clearing doubts.
• Role of Seniors: Beyond the courseware, seniors help their juniors in various aspects such as interview preparation and expand their knowledge beyond the course material. For these purposes, there is a computer club on the campus.
• Tech Fest: Avishkar, is the name of the competitive programming event held on the campus. Competitive programming events are held which are well-organized and contribute to the learning of the students.

I have a few friends pursuing CSE at MNNIT Allahabad and they vouch for the course. 

It seems like you are a fresher to the college and desperately wants to change your branch Biotechnology, which is the most underrated branch of the college, compared to some other branch.

To be precise, a CPI of 8 is considered safe. Try to keep it above 8. But, if luck is on your side, even a CPI of 7.6-7.7 will help you out.

I would like to mention a few points that you should consider before switching your branch and perhaps, these are the reasons that make Biotechnology at MNNIT Allahabad amazing.

• Faculty: The faculty members are very good. They are comparatively young and therefore understand more of students’ problem. They are friendly and approachable, which is unique to the Biotechnology department.
• Class Strength: There are around 35 to 40 students in the class. Because of the lesser number of students in the class, all share a good bond within themselves as well as with teachers. This is significant at good and bad times.
• Research: The department is very active in the case of research. The department has received funding from various government agencies such as DBT, DST, UGC, MNRE, etc., and has published research papers in national and international journals of repute. Externally funded research grants of approximately above 1.5 crores were also generated by the department within a short span of time.
• The infrastructure is good and growing rapidly.
• Ample placement opportunities. Students are either placed in good companies or they opt for higher studies.
• Students from the department also succeed in exams such as GATE, GRE, CSIR-UGC (NET).

The faculty also frequently visits other research laboratories and research institutions in the country and abroad. Additionally, national as well as international conferences were held which were government agencies supported.

When computer science was first introduced in India as a course to pursue, it was launched in only two colleges namely, IIT (Kharagpur or Kanpur) and MNNIT Allahabad.

It was a five years course in the former while in the latter it was a four-year course.  Therefore it can be said that the first batch to launch in the market was from MNNIT Allahabad.

CSE in MNNIT Allahabad is the best branch among all the branches. The reason is stated below:

• Good placement: In the placement drive 2020, 96.42% of students out of 168 eligible students got placed from the department which stood just after the IT department. The average package is the highest from the CSE department which is 18.02 lakhs per annum. The highest CTC offered was 39.002 lakhs which is the same as the ECE department and is the highest among all other departments.

• The coding culture here is very good.
• The faculty is quite good and friendly. Also, you will get a competitive peer group. 
• Ragging is not tolerated in the institution.

Hope it helps to get an idea about the CSE branch of the institute.
