Noida

First and the foremost thing, if you have a JEE Mains rank wherein you can get any government college, go for that.
Next, let's come to the topic of JIIT, Noida:
JIIT has two campuses in Noida i.e. Sec-62 and Sec-128, wherein Sec-62 is considered better in terms of faculty, placements and overall stats.
So, is JIIT worthy of 12 lacs?
If you are planning for a private college, then I will recommend that JIIT is good for you. Spending same or more amount and taking admission in colleges like Amity, Sharda, etc., is no use.
JIIT offers a good campus (a bit small), decent infrastructure, decent faculty, good hostel facilities, a very nicely structured curriculum and yes, secured placement.
If you have fancy dreams about your college, then JIIT is not for you.
JIIT has a good name in Delhi/NCR. According to me, it's a good choice for those who have secured around 50K-60K rank in JEE Mains and are looking for a private college.
Spending 12 Lacs is heavy, but you'll be at a good place.
