CBSE 12th

Hi Anushree,
There are various career options available these days. However, I would recommend that you first concentrate on your 11th standard as it is very crucial in setting up a firm foundation.
Before you decide what to do after 12th standard, it is important that you become aware of a critical factor for success in your chosen profession. Your exam scores are one part of it considering how competitive it is to land a seat in the hallowed campuses of the IITs and other prestigious institutions.
With the combination of biology, physics and chemistry you can take up medicine, dentistry, Pharmacy, agricultural science, dairy science or biological sciences (biochemistry, biotechnology, Microbiology). Apart from doing the degree level courses in science with the conventional combinations you can also choose degree courses in several emerging professional areas, such as physiotherapy, occupational therapy, nursing, computer, business administration, hotel management, tourism management etc. you can also opt for courses outside the university stream, such as hotel management, fashion technology, industrial design, packaging, aircraft maintenance engineering, government accredited computer courses and a host of post 10 + 2 level vocational courses. For pursuing a course in engineering, you should have Maths as compulsory subject in 10+2.
However, All India Institute of Medical Sciences, New Delhi (Website: www.aiims.ac.in or www.aiims.edu), offers B.Tech (Biotechnology) with Class XII with Physics, Chemistry and Biology. To get admission in the top medical college in India you would need to score above 90% in 12th and do very well in entrance exam.
With a PCM combination of subjects, you can pursue almost any field you set your mind on. You can ofcourse do engineering which is a professional degree and has streams such as Electrical, Mechanical, Electronic and Communication etc. You can do your graduation in subjects of your interest, even switching to humanities or commerce streams if you so desire.
You can do a BCA (Computer Applications), BBA (Business Administration), law, civil aviation-pilot, astronomy, architecture, design, mass communication, merchant navy, defense forces, psychology, civil services etc. To decide on the course, you should analyse your strengths, career goals, interests, personality, aptitude and ability.
If you decide based on these parameters, you will put in your best efforts and will be successful in your chosen field.
