CBSE 12th

Hello Naga, Madras Institute of Technology is good choice for pursuing aeronautical engineering. You should have to clear the cutoff declared by the MIT. Go for TNEA counselling conducted by Anna University.

Any college who's cut off is 62 percent will admit as NIOS is an approved board under MHRD.

You have scored good marks.Why Shiv Nadar? Join any NIT or IIIT.Can you tell me your rank so that I can suggest you few colleges according to your marks.Thapar University, Patiala and LNMIIT will be best for you.These two colleges are far better than Shiv Nadar University.

B.Sc in Physics, Chemistry, Polymer Sciences, Nano Technology. B.Tech, Geology, Psychology, Actuarial Sciences, Anthropology.

Hi, your query is incomplete. Kindly mention your stream.

Hi,
If you have cleared your 12th from a full-time board such as CBSE or ICSE, etc., you have to re-appear for the same from the same board unless you see no scope for improvement, in the latter case, you can enrol into NIOS and repeat your class 12th.

Hi,
Rather than the best, I would focus on the more popular options. Best could vary from person to person and will depend on one's skill set.
Biotechnology
Bioinformatics
MBBS
Biology
Genetic Engineering
Biomedical Engineering
Health Sciences
Physiotherapy
Pharmacy
and many more.

Yes, you are eligible to study B.Com. But, somewhere you'll get problems about basics of commerce as it I cleared in +1and +2. But, if you give some extra time and put enough efforts then it'll be easier for you.
Good luck.

Hi,
Please define ' good career'. Your answer will depend on the kind of 'career' you want to be in. There could be numerous options depending on your education background. Most importantly, you need to know your own interests and areas of strengths. Since your query is incomplete without any mention of your academic details, it will be hard to counsel.

Hi,
Every college has its specific process and merit list. You have to keep checking the websites for notifications. Earn a degree in management, you may specialize in sales. For better prospects further, pursue a PGDM in sales or pursue an MBA.
