You can opt for MBBS, B.Pharm or B.Sc in agriculture as all three have good career prospects.

Yes, you can get B.Tech CSE in Amity, Noida as the eligibility is 60% marks (PCM and English) for general category candidates.
JEE mains: Students securing a score of 30 and above in JEE Mains 2017 plus 60% in E-PCM (English+ Physics+ Maths+ Chemistry/ Biology/Computer Science/ Biotechnology), will also be considered as eligible for direct admission process i.e., exempt from entrance test and interview for B.Tech programmes only.

It all depends on your AIR. Given that, you got 71% in JEE Mains, I am assuming you have a score of 255-256 which brings you a rank of around a maximum of 3K which means you have a guarantee to get in DA-IICT. The cut-off ranks are around 12K.
Hope this helps.

As I can see that, your scores are good. I don't think you need to drop a year. Did you appear for any entrance exam?

Hi Isha,
There are states in India such as Tamil Nadu that offer admission to engineering based on class 12th PCM scores. There is no state entrance examinations in such states.

You just need to get a mere 80-82 percentile to clear the cutoff and then you have to excel best in the IRMA Aptitude Test and then convert it with your expertise. Upvote and follow if found useful.
