Ayushi, 

To get jaypee noida cse you need a rank of around 50K in jee mains. If your rank is 50K+ then it is difficult to get admission there. 

Assuming you can get jaypee noida then i would say Jaypee Noida is a good college no doubt... Plenty of companies visit their campus like Google, Microsoft, Flipkart, AmazonEpic System and other tech giants and mass recruiters like TCS wipro. Last year stats show that avg package at Jaypee noida main bramch was above 7lacs. Which is good. 

If you want to drop you can but taking a drop will add a huge amoount of pressure on you. Taking into consideration this year rank vs marks no score is safe except above 260 and it requires daily labor in addition to dedication and focused mind. I know some guys who got 220 marks and got 21K rank and that rank won't fetch you a great nit. And if we talk about jee advanced it's much harder than mains. 

I can't pass a judgement... But I think if you are not that type of guy whi can study for 10 -14 hrs a day you should not drop a year and you should take jaypee noida cse.
