Hi Balu,
Since you said you like making both electronic model items and also mechanical works, so you may consider giving entrance exams and opt for engineering, though doing engineering has a value only if it is done from a good college. Since you like both, I will try to make your path clear. ECE is a good branch with a lot of scope in private sector companies. But to survive in that you need to be really skillfull and need to keep yourself updated. On the other hand, if you choose mechanical then there is a lot of scope in government sector in India.
So, if you can't decide which thing you like more, then decide from the scope and future prospects.
