See, you are not alone and many people are in the same situation as you are currently in. So, since you have taken Science stream in your class XII, then I would suggest you to continue with the same field as now switching into some different field will require a lot of dedication and then mastering it would prove to be very time consuming.

Some of the best options that you can pursue are as follows:

1. Do a B.Tech in any of your favourite branch

2. Pursue a B.Sc degree and do masters later

3. Do B.Com (//B.Com) and hunt for a high paying job after completing it

Hop I have made your options clear. All the best!
