The first step in becoming a software b tech course after 12th is to enroll in a B.Tech program in computer science or a similar discipline. The fundamentals of programming, data structures, algorithms, and software development are taught in this four-year undergraduate program. Passing entrance exams like JEE Main is typically required for admission. Emphasize practical skills throughout the course by participating in hackathons, coding projects, and internships. You can raise your profile by learning extra programming languages and tools outside of the classroom. You can work in software development after finishing the B.Tech course after 12th, or you can go on to further your studies to become a specialist.
