Hi Alentine, to pursue studies after 10th abroad you must enroll into high schools where you can complete you can 11th and 12th grades. Take the IELTS or TOEFL before applying, these are tests for English language proficiency. You must check the colleges and contact them directly for other requirements as they vary, email or call them, they are very helpful and have dedicated officers to support international students.

You should try for B.Tech. B.Tech is better than B.Sc. You can join a good college and work hard.

It depends on your category. If you belong to SC/ST category, then don't worry. If you belong to OBC or general category, then you appear for improvement exam.

Your score must be 85-95% in boards for top ranking colleges like, Harvard and Stanford University and also for scholarship.

Hi,
You can pursue a degree based on your interest. As your favorite is biology, go for B.Sc in zoology, biotechnology, etc. Class 12th is not enough to make a better career growth. Don't jump to get a job. First, study and update yourself and then go for a job.

Yes, you are eligible.
