Hey Govind

If this decision is your then you must go with your decision. If you are not interested in continuing in commerce the surely you should change and it's a big decision to repeat 1year and if you are ready the move on .

You must always choose that subject in which you are interested because if you will show interest in that particular subject then there will more chances to Excell in that field so you must choose that path which you can follow , so good decision move on.

All the best

I would suggest you to continue with commerce.Because the scope of engineering is going down day by day(By scope I mean economic status)as people are earning just 40000-70000 pm after working for like 15 years

Hi, You are interested in Science and you are ready to repeat your 12th. Yes you will waste your one year. You can do your 12th in Science from open board incase that is your will. Or else you can repeat a year and work hard so that you get science stream. It is a risk so work accordingly. Good Luck.
