Hello,
First of all try to prepare for engineering entrance exams like jee mains,viteee,srmjeee,comedk,wbjee,etc and try to get admission in a good engineering college to get admission in software engineering or computer science engineering.
Books you can refer to at this stage is E.Balagurusamy C,C++ and Java book as these will help you to study about different programming languages.
Good luck.

I want to be a doctor
