Sudipta, 

Jaypee Noida takes admission through Jee Mains.  In order to get CSE you must get the rank around 50-55 thousand in jee mains. 

Where as galgotia college of engineering takes admission through UPSEE(up state engineering exam)  amd you need to get good marks in that. It also takes admission through JEE Mains.  You need to get around 90-100 to get admission there. 

Now comparing the college for CSE, Jaypee noida is far much better than galgotia in terms of placement. 

In JAYPEE NOIDA ,dream companies like Amazon or those offering a CTC between 6 LPA to 12 LPA (SAP, Deloitte, Zomato and a few more) then you should for CSE/IT at Jaypee, Noida. Average package is around 5 lakhs. 

Whereas major IT companies Don't come in galgotia and average package is around 3.5 lakh. 

I would suggest you Jaypee.  Rest depends on you.
