Hey!

I don't think you can pursue science by doing 11th again after completing your class 12th in commerce stream. There are certain disadvantages to that:

• You will have to spend two more years in just completing your school
• You will have to specify the reason why you took two more years in finishing school
• You will few steps back in your career owing to the age limit in certain cases

Though if you really feel that you want to make your career in science and related fields, you can go for it. Just make sure to weigh all the pros and cons and then take your decision.

Best wishes!

Dear Aditya,

''change the subject is like this crazy'' that people said what you should do what you want and you may also ignore them and Yes, you can change the subject or we said you redo 11th with commerce even you try different one also, In case you interested and you take Science after doing commerce in 12th.

All the best.
