Hello dear student,

If you want to become a software engineer  then you must have computer science or maths with science in your class 12th. You can opt for BTech computer science b tech information technology as your trade subjects in  your graduation. Then you can give different entrance test in different colleges otherwise you can directly give JEE mains and get a good score in JEE mains and you can apply for different private colleges or NIT's and even some really good government college to get these subject. Then you can do specialisation if required to become software engineer. I hope this was helpful

Best wishes
