Hello,

You will have various options after 12th.Generally science students have much wheightage in terms of job but its not always true though.Nevertheless you will have wide range of options but it all depends upon you that in which area you want to study for future and where you are really interested in. You have taken computer so if you are keen to study computer then you can make career in that by doing BCA after 12th.Ofcourse you have option for persuing engineering too.Apart from that you can do BBA,Hotel management,CA,designing,government jobs and so on..!
So, just sit and think what you really like and what you really want to do.

Goodluck
