Hi there!!!

As you are interested in career options after class 12th other than engineering so there are many options after completion of 12th from Physics,chemistry and mathematics .
Computer Application- If you are interested in computers and designing applications or software, CA is a great option. You can pursue either aB.Sc. in Computer Application or a BCA.
Aviation- You can choose to become a Pilot or an Aircraft Maintenance Engineer (sorry for the engineering part). To become a pilot, you will have to take an entrance to get through a flying college.
Architecture- If designing is what you are interested in, Architecture is a great field. If you manage to score well in NATA/JEE, you will be able to get through the finest architecture courses
.Merchant Navy- This is also a good career option for science students. You can get aB.Sc. in Nautical Sciences or join directly after 12th if you want to make this your career.
Defence Service- You can also join the Indian Army or Navy if you do not want to pursue engineering. It is great option and you get to serve your country too!Allied Fields- You can also go into the research and development field, by pursuing aB.Sc. in Mathematics, Chemistry or Physics. If you are interested in research and academia, then this also a rewarding field.
Ethical Hacking- If you are the sort of person who is intrigued by this field, you can also become a certified ethical hacker. There is no preliminary qualification that you will need to become an EH, only knowledge of programming language and operating systems.
