Dear candidate out of NIET and Galgotias College of Engineering it would be better to choose Computer Science engineering branch at NIET.

Since you will be a lateral entry student you need more knowledge and guidance from the Faculties. Your academic life would be pleasant, starting package of salary can vary from 2.5-4 LPA. But if you are really interested in ECE Subject then I would not induce you to take admission in NIET rather you can proceed with Galgotias.

Good luck!!
