The crowd for engineering in RV College is more competent and of better quality than IEM. The reason being that RV College admits quality students as per the COMEDK ranks that are usually within 1000. The CSE branch records even higher competition as the cut-off rank is 500. IEM College accepts students to 3000 rankings in WBJEE.

Overall, the above points highlight the RV College is anytime better than IEM.

IEM is ranked 3rd best for engineering in West Bengal and ranked at 79th position all over India. UEM is ranked 96th for engineering by Times 2020. BCA has a more software-based approach whereas B.Tech includes learning of both hardware and software.

Admission: The admission to BTech at UEM and BCA at IEM is through IEMJEE. The prerequisite for the programs is 10+2 from a recognized board. The cut-offs are declared at the time of admissions.

Placement:

UEM- It has a placement percentage of 123%; almost all the students get 2-3 job offers.

• The average package is nearly 4.2 Lakhs per annum. The highest package offered was 40 Lakhs per annum.
• Top recruiting companies of the college are TCS, Wipro, Videonetics, Codeclouds, NRI Fintech, Think analytics, Global Logic, etc.
• A BCA graduate gets an average salary of 2.5 Lakhs per annum.

IEM-

• For IEM Kolkata, the top recruiters are Deloitte, TCS, CTS, Infosys, and Capgemini.
• According to 2019 placements it had a 100% placement rate.
• The highest CTC offered was 15.5 LPA.
• The average package for IEM is 4.2 LPA.

Both UEM and IEM offer similar placement opportunities but as a course BTech offers more scope as compared to BCA. However, you should be the one to decide which course will be better for you.

My sister graduated from IEM Kolkata in June 2016 and she is now working as a consultant at KPMG. She shared some of her experiences and the basic do’s and don'ts she followed while studying there.

• IEM Kolkata is very strict with its college timings and the students have to be very punctual. She suggested that they must reach college before 9:10 AM as the morning assembly starts at that time. Or else they can enter the college only after lunch time which starts at 12:20 PM. 
• All the students must maintain attendance of minimum 80%. This is very important as students will be prohibited from giving exams with lower percentages of attendance. 
• The students should submit all their projects, assignments and reports to their respective professors on time to maintain a good image in the college. This can be very crucial while getting internal marks which increases the overall marks in final exams. 
• The students must be able to build a good relation with their professors. This can help a lot in the long term to get many information about higher studies and their recommendations helps a lot in deciding the right college or career for our future.

Maintaining good grades is very important because students with lower grades are considered not capable enough for placements in top popular companies. They can sit for placements at non IT companies though. Students with lower grades don't get good opportunities in the college so one must maintain above average grade in his/her subjects, to secure a placement or even opt for higher studies.

The top recruiting companies that participate in their placement program include, Google, Microsoft, Accenture, Capgemini, L&T, Wipro, TCS, Mindtree and many more.

It all depends on the candidate’s decision. What may seem productive for him might fall flat for others.

Here pointing few specifications which might help you choose:

• IEM is a Private engineering College whereas; KGEC and JGEC are government owned colleges.
• Annual Tuition fees are far less for both the government colleges and IEM being a private institute holds higher fees and increases cost of living.
• Being government owned colleges (KGEC, JGEC), the student from financially weaker section is subjected to stipend, half-fees and full fees consideration.
• If we take a look at the campus location, IEM is situated in sector-V, in the crux of the IT revolution which began at Kolkata. Whereas, KGEC, JGEC have their own campus located outside of the main city.

IEM being a private institution is strict with its studies. But, being government colleges students can see little slack on education in KGEC and JGEC.

If campus recruitment is the sole criterion, then IEM stands out with a virtuous record. Whereas KGEC and JGEC in can see slack in core branches recruitment.

IEM being situated in the heart of the city’s IT sector, all the companies take interest to see the students from IEM. KGEC and JGEC located outside the main city.

If you compare KGEC with JGEC, KGEC is the way to go. KGEC has a better ratio of placements, infrastructure, facilities, and faculty than JGEC.

Choose KGEC if you want to study in any core department. Otherwise you can choose between JGEC and IEM for other departments. If you are looking for government jobs, KGEC is the one. Choose KGEC without hesitation. If you don’t get a chance to get into KGEC go for JGEC as both being government colleges gives less burden of fees and expenses.

Finally, it’s up to you to choose any one among the three engineering colleges. Based on the parameter, it drives your decision. My suggestion would be go for KGEC and if not then, JGEC over IEM.

IEM Kolkata organizes many fests and competitions throughout the year. The IEM Kolkata fest is organised every year and it is known as Innovacion. It is being celebrated at a large scale and many performances, from dance to drama are performed here. All students from semester participate in this fest and together they make it a successful one.

The college also organises fresher's parties and annual functions at science city auditorium. At the fresher's party, all the newbies are welcome and they introduce themselves to their professors and seniors. These events turn out as a great refreshment for the students as the students have to go through a lot while studying and complete all the projects and assignments and attempting exams all together. 

The events are necessary as it encourages the students to learn some new things like time management, discipline, teamwork and students can also showcase their talent to the world by performing in these events.

IEM Kolkata as a college is just focused on getting marks and secure jobs during campus placements rather than providing quality education to its students to get some knowledge. The students were told to sit in campus placements with UEM students which was considered to be a very dis-organized step taken by the college.

The environment inside the college is very bad and the curriculum for students is worse. My sister studied here and she mentioned how the students are only concerned about getting any kind of job during the campus placement so the institution can maintain their reputation resulting in more admissions in the coming years.

They don't care about improving the knowledge or skills of a student. The rules of the college are really difficult sometimes. Like if you're seen at the library you can be restricted for bunking class. Also the teachers are very rude and the students are scared of them.

These things leave a bad impression on the students about the department and the college too and ruin the name of the college. These problems should be solved immediately and not only in this college, it should be fixed in every college where such things happen.

The hostel life at IEM Kolkata is believed to be very bad. The food that is served to the students is very unhygienic, unhealthy and tasteless. It is very bad and many students have to order food from outside the campus. The students complained about this issue to the authorities but there was no change or improvements. 

The hostel fees are pretty high but in return the facilities provided to the students are very poor. The wifi is also poor in speed and most of the time it didn't work well. Also the limit is only 4GB per month which is very less data in today's world as we need the internet for a lot of things.

They have a strict rule of entering the hostel by 6:30PM which is pretty early. So the hostel life will be very bad and it will be better for a student to stay in rent or PG outside the campus.
