I feel LMNIIT CSE is a much better choice than NIT Agartala CSE provided that you have the financial means to get admission there. Here is why I feel it's better than NIT Agartala

• LMNIIT has a more updated and flexible curriculum than NIT Agartala. 
• LMNIIT has a better crowd since the admissions are purely based on merit and there is no reservation policy.
• Many IT giants visit LMNIIT every year for placements which isn't the case at NIT Agartala as the job opportunities are limited there. 
• Jaipur has better opportunities for preparation for competitive exams like CAT and GRE.
• LNMIIT is not a private college but a Public Private Partnership so you will avail the benefits of this high brand value in the industry.

So, is better to look beyond the NIT tag and choose LMNIIT because the tag does not matter much more than academics and placements.

Honestly speaking all the B Schools you mentioned are just glamorous brand names with no real value. The placement scenario is very pathetic here as the companies that visit are looking for students who can work at fewer salaries. Only the extremely meritorious students get good packages and that too is rare.

So I will suggest that if you have scored 95+ in CAT, then you are capable of more. So work hard and target a better B School next year. Remove these colleges from your list of options and attempt CAT again.

If you are not very sure about attempting CAT again then prepare yourself for a package as low as 5-6 LPA.

To help you choose between UIET and Thapar University, here are a few comparisons-

• Infrastructure- The infrastructure of UIET is not good. Thapar University has a good infrastructure and you will really like it when you visit the institution. Also, do check the pictures of Thapar on instagram.

•  Fees- The fees for Thapar University is extremely high. On the other hand, UIET fees are so affordable that you won’t even feel like you are paying college fees.

• Research- Panjab University is doing good in the area of research. But UIET in itself has not produced much output yet. On the other hand, Thapar excels in research quality. However, PU has a government funded innovation center and you may get an internship over there. This makes UIET also a good choice for a career in research.

• Brand Value- Panjab University is a big brand. However, its Engineering department is not as well recognized. Thapar is a well known engineering institution that has a high reputation in North India. It has a brand value at par with BITS and NITs.

• Alumni Network- UIET is new and has virtually no alumni network. Thapar is old enough and has a wide alumni network spread across various countries.

Thus, after considering various parameters, I would suggest you to opt for Thapar University for your CSE if its high fees is not an issue.

Without any second thoughts, choose KMC Manipal over HIMS Dehradun. Joining a private college is not considered very wise but it’s not in the case of KMC because 

• Its crowd quality is exceptionally good. It's an old college. 
• It’s one of the oldest private medical colleges and most Govt Colleges so it has come to establish a reputation of its own.
• It’s the only private medical college that has churned out so many generations of successful doctors.
• It offers excellent medical education and its fees are comparatively less than other private colleges. 
• The institute boasts of a well-equipped sports complex called MARENA.
• An amazing campus life with enough exposure to extracurricular activities. 
• The Manipal campus is extremely beautiful and offers a good academic ambiance.

Overall, the opportunities this college has to offer make it an excellent choice. 

Choose the course that interests you, college is a secondary thing. Here are some of the facts that may help you in choosing the right branch for you.

• If you want to work in PSUs or Govt. sectors, it’s better to not choose Production Engineering as there are fewer recruiters.
• Jadavpur is the best college you can get through WBJEE. If you choose Production or Power in JU, you will have good on-campus job opportunities.
• Production Engineering is a branch of Mechanical Engineering itself. The syllabus will be more or less the same. 
• Mechanical at Kalyani University will be slightly better than Jalpaiguri. You may not get lucrative job packages at on-campus placement from Kalyani University but in the long run, you will have a much better hold with your Mechanical degree. You can expect well-paid jobs in the future. 

Your future will depend on the branch you are choosing so choose according to your interest. All these Universities will offer you enough opportunities and resources to prosper. It’s up to you to use that well. 

Both NIT Trichy and BITs Pilani are prestigious institutes offering high-quality engineering education. Moreover, CSE and ME are equally good with different opportunities and prospects. So the choice between BITS Pilani CSE and NIT Trichy Mechanical depends on what your preferences and career prospects are. 

BITS Pilani CSE is a great option if 

• You want to join a top private organization like Google, Facebook, Quora, Amazon, Microsoft, etc 
• Your primary goal is getting high packages even at the cost of extreme work conditions and workload
• If you have a strong passion for coding
• If you have no financial constraints and can afford the high BITS Pilani fees.

However, NIT Trichy Mechanical is a good option if 

• You are looking for a stable Government job through UPSC Engineering Services Examination 
• You want to go for PSUs such as IOCL, ONGC, NTPC, etc through GATE 
• If you are a research enthusiast and want to work in a research-oriented government job as a Scientist or Engineer in organizations like RDO, ISRO, BARC, etc
• If money is your secondary preference and you primarily focus on attaining a better work-life balance.
• If you have financial issues and BITS Pilani fees are out of your budget.

Ultimately, it’s you who can decide the right college and stream for yourself. Just remember that these are just stepping stones to success and it’s you who has to work hard to become successful. 

In terms of placements, environment, alumni network and infrastructure, BIT Mesra is a much better choice than NIT KKR. BIT Mesra is quite an old institution and its alumni are spread across continents. One of its alumni won an Oscar for his work in an animation movie a few years back. BIT alumni hold good positions in top IT brands like Facebook, Google, Amazon, Microsoft, among others.The placements at BIT are quite good with the average package for B.Tech CSE recorded at INR 19.27 LPA for 2022. Many CSE/IT students receive multiple offers during placements. Last year, 113 CSE students were placed out of a total of 124 eligible students. Top IT and non-IT brands visit the BIT Mesra campus for placements.

BIT Mesra students perform well in ICPC and GSoC. The coding club ACM organizes a weekly coding contest within the campus. BIT has been a national winner in several coding contests like- Goldman Sachs’s “We Build” coding contest(BIT was a winner in all the three formats), Smart India Hackathon, etc.

The tech clubs over there like IET, IEEE conduct free workshops regularly to improve the technical skills of the students.The senior-junior interaction is very healthy at BIT Mesra and there is no ragging on campus.The cutoff for BIT Mesra is not that high because its fees is much higher than the NITs and it does not carry the ‘NIT’ or ‘IIT’ tag

Unless you want the NIT tag for your higher studies, you should choose BIT Mesra over NIT KKR for your CSE. The former will help you in developing your skills and you will get better placement opportunities at BIT Mesra.
