The above answer is based on the reviews of my friends who are alumni of IMS Noida and are successful today. It's a very unbiased review and intends no criticism of the institute. 

The primary 3 aspects that are the foundation of any college are its students, teachers, and infrastructure. So I will be writing the review based on these aspects only.

Teachers

There is a big difference between being qualified and being a good teacher. While most of the teachers are highly qualified, only a few are good teachers. Some teachers that genuinely care about the students and try their best to bring good results out of their students are 

• Sudhir Sir and Nancy Maam
• A very practical Maths teacher Pankaj Sir
• Very emphatic teacher Rashmi Maam 
• Barshma Maam who organizes cultural events.
• Apart from these gems most of the teachers are full of ego and lack sympathy. The teachers do not motivate startups, athletes, or extracurricular activities and merely involve themselves in robotic teaching. There is no structured pedagogy and teachers are very lethargic. The syllabus is outdated and all this affects placements largely.

Students

Obviously under the guidance and training of such an average college, the quality of students stoops low. Most of them are lazy and just mug up concepts. But there are a few who want to strive hard but the lack of necessary resources does not let them excel.

Infrastructure

• The computer labs have very old systems and the speed of the internet is extremely poor.
• The classrooms lack ventilation and there are no microphones for lectures. 
• The wifi facilities are extremely poor and students hardly have open access despite paying fees for the same
• The toilets are unhygienic and dirty
• The library has a good collection of books the only drawback being no reminder system for renewal of books

All these points are genuine and not based on any official data.
