Hello apsirant,   

For IGDTUW: Well ventilated buildings, large campus, the construction is of British Era.The labs were well equipped. Professors have in depth knowledge of their subjects and they impart it perfectly to students.Mechanical has seen a placement of 8lacs p.a for CS is like the above 10lacs p.a. is normal and has touched 20lacs p.a

For IET:  it has managed to secure the second rank among the engineering colleges of uttar pradesh state. Placements are good. on an average it is 3-4 lakhs and with good skills and experience it can go upto 7-8 lakhs.

These are some basic differences in the colleges. Now you may choose wisely.

Thank you!!
