It is recommended that you opt for an institute based upon its Affiliations, Accreditations, Placements, and Extra-curricular activities. Since one of my friends is a student at IITM Janakpuri, here is what she says about the institute as a whole, 

1. IITM Janakpuri has been developing at a steady pace ever since its establishment, in terms of its academic quality, and the number of students.
2. In fact, IITM Janakpuri has been accredited grade “A” by NAAC. Moreover, the institute is affiliated with IPU Delhi and is simultaneously also approved by AICTE.
3. The major upside is that students from IITM Janakpuri secure placement offer from several top-ranked firms around the world, including Jaro Education, HDFC, RBS, Tech Mahindra, Genpact, etc with reasonable salary packages.
4. Moreover, the institute will encourage you to take part in various inter and intra college Extracurricular activities as well. 

Having said that, every institute encourages 10% of the total number of seats through the management quota.
