I can give you some information on both institutes since I have friends from both IET Lucknow and JSS Noida. Based on the reviews that I got from my friends I will say choosing JSS Noida will be better. It has a locational advantage, which plays a crucial role.

• The curriculum of JSS Noida is in accordance with the current industry trends. In the first two semesters, you will learn the same courses as any other engineering institutes in India. You can get the detailed syllabus from the website.
• JSS has a good reputation in the industry. Alumni of the institute are working on Google, Microsoft, etc. Many reputed companies visit the campus for the placement drive including IBM, Wipro, TCS, Amazon, etc.

For IET, the location is an issue. The faculty and curriculum are not that great either. So, I will suggest you choose JSS Noida.

Considering this question, the first thing that can be highlighted is that both of these institutes cannot be compared at all. However, studying IT in IIIT Allahabad is far better as it offers several opportunities, as well as institutional environment and infrastructure to assist the student in their career growth appropriately.

However, CSE at Vellore Institute of Technology (VIT) is not so secure considering the programming prospects and study culture that the student will get at IIITA. This choice is easy enough for the student to make as per their career perspectives. 

The following table gives a brief overview of these two institutes:

Thus, considering the above facts, it can be stated that between these two institutes, the student must go for IIIT Allahabad, as VIT can’t be compared at all.

Sharda University has been awarded the best private university continuously over the years by National Education Awards. It has also been awarded the best Private Global University of the Year and the Best Innovative Engineering School in North. It is ranked 151 out of 200 by NIRF 2020. CSE department is one of the best departments of Sharda University.

Curriculum:

• The CSE department aims at providing an industry-centric curriculum and provides a blend of classroom and experiential learning.

• They include lab exercises, assignments, case studies, and work-integrated activities.

Admission:

• Matriculation with-60% marks, 10+2 with 70% aggregate and minimum 60% marks in PCM, Computer Science/PCB for Biotechnology without a gap between 10th and 12th is the required eligibility.

• Students can also appear for Sharda University Admission Test (SUAT) if they have scored above 50% marks in Maths in 12th Boards for selection.

• All students up to JEE rank of 3 lakhs and students with UPSEE All India rank up

to 50,000 are also eligible for admission.

Placements:

Sharda University has an excellent track record of 91% and 100% placements over the year. Most CSE students get an above-average salary package due to the demand of their course.

• The highest salary package was 64 LPA. Every year about 350 employers recruit students through campus recruitments.

• Some famous recruiting companies include Amazon, iGate, Wipro, Edelweiss, ITC, L&T, Audi, Asian Paints, etc.

The department provides compulsory internships in the final year and for students who perform exceedingly well get the opportunity to participate in a full-time summer internship in USA, Germany, Mexico and Australia. They also give regular industry visits.

Yes, IIIT Lucknow has a better package for CS and IT students than IIIT Allahabad and IIIT H. However, it will not give you a guarantee that you will get placed after completing your studies from IIIT Lucknow.

The following table will show you the placement record of IIIT Lucknow.

IIIT Lucknow has been established over many years, and is one of the oldest campuses of IITs. The Lucknow campus is from one of the top 5 campuses of IIT and probably the best one. It grew fast as compared to any other institutes 

The average salary offered to IIIT Lucknow students is INR 18.42 LPA, while the highest package goes to INR 43 LPA. The Median package is INR 15 LPA, and the minimum package offered is INR 10 LPA.

Seeing the current scenario, in future also, IIIT Lucknow will give good placement to its students. 

Therefore, if you are thinking of joining IIIT Lucknow then go for it. Because apart from having similar faculty to other top institutes, IIIT - L provides students to improve their technical and soft skills. And that improves the chance of their placement.

According to the 2021 WBJEE cutoff, the required cutoff for CSE at Heritage Institute of Technology is 3434 (general). So, it will be difficult to get admission in CSE with your rank. As an alternative, you can go for IT at Heritage. It offers similar career prospects as the CSE branch. 

With 4.5k rank, you can also try for KGEC EE/JGEC CSE/GCECT CSE/GCELT CSE/IEM IT/ GCETTS CSE.

At this rank in case, if you are getting a Govt. college don’t go for it as there is a very low chance of placements.
