Hi Yuvraj!

According to your query, you have joined non-medical stream (PCM) subjects in 11th and 12th class. There are many optional subjects which vary from school to school. But the most pouplar and most common optional subjects are computer science, physical education, painting and music. All mentioned additional subjects have theory exam of 80 marks and practical exam of 20 marks except music which has 70 marks of practical exam and theory exam of 30 marks. I would suggest you to join computer science as computer is needed in every career. If you are planning to take two optional subjects then you can take computer science and painting/music. You can obtain full marks in painting or music which will help you to maintain your grade even if you are not good at computer science.

Hope I answered your query, thankyou!
