You must pass the entrance tests conducted by the respective institutions or the common entrance test conducted to pursue B.Arch i.e. NATA National Aptitude Test in Architecture. I. Student must have scored minimum 50% aggregate marks in board examination from a recognized education board. The minimum score range may vary from one institution to other. Ii.

There are so many options like MBBS (Bachelor of Medical and Bachelor of surgery), BHMS (Bachelor of Homeopathic Medicine & Surgery), BA MS (Bachelor of Ayurveda Medicine & surgery), B.Sc Agriculture, B.Sc Zoology, B.Biotechnology, BE in Man Made Fiber Technology, Microbiology etc.

Yes, you can study.

If you interested in Medical field then go for the preparation of NEET and other state exams. Otherwise, go for B.Sc.

Yes, you can apply for BCA as you have completed class 12th.

It's average score. Since ICSE paper setting and correction are very liberal, 82% is just an average score. When my daughter completed class 10th in 2014, around 70% of students scored above 80% in her school.
Any way you can always work hard and do much better in your future exams.

Hi Abhay,You can go for any honors courses like physics honors, math/bio/economics/political Science/history honors. Even, you can do BBA BCA B.Com also. There are lots of opportunities available for you. Don't feel low due to low marks. I have seen people with 50% marks, who cleared UPSC and now they are IAS/IPS officers. Best of luck.

Your hard work can make you do anything. Do not fear because of your marks. Go according to your interest and you will succeed. Apart from this, you can go for B.Sc and then M.Sc. You may become a teacher in school which is an easy option for an average student abd serve the education system.

Usually, no entrance examinations are conducted for enrolment of the students to the B.Sc Study programme.
