Hi Shiv Das,
71% is a good score. You will find many options but it will be a challenge in Canada, still, try.
Check the skill shortage lists of the country for opportunities in mining. International students must take IELTS. Some universities may require GRE. Excellent SOP and LORs will be required.

B.Sc. Agri doesn't require NEET score. You should go for a good college.
All the best.

Hi Desai Ishani,
If you have a good profile, you can stand a chance to get a scholarship from the university abroad. They are usually on merit basis. Banks in India like SBI, PNB etc. also provide education loan which you can repay after you get a job in 15 to 22 years. Besides, there are organizations like Aga Khan Scholarship, Mahindra Trust Scholarship to study abroad.

The cut-off of Delhi University is irrespective of the board, so it totally depends on your best four %age in 12th whether you meet the requirements of DU or not.
You can check out the previous year cut off to get an idea of 2018 cut off-

Hope this helps.

According to the eligibility criteria, the candidate should be a graduate or should have pursued a degree in any discipline from any recognised university in India.
Final year candidates can also apply.

B.Sc. (Hons.) is much more specialised as compared to the B.Sc. (General) degree, and academically, B.Sc. (Hons) is a more standard degree as compared to B.Sc. (General).
If you want to study any one of the main sciences (eg. chemistry, physics, mathematics, etc.) in detail, it is advisable to go for a B.Sc. (Hons.) course. But if you want a more balanced and multi-disciplinary approach, it is better to pursue a B.Sc. (General) course for under-graduate studies.
Best of luck!
