Sri Annai B.Sc is a science field which revolves around the pure science subjects (Physics, Chemistry, Biology) and with B.Sc you will not at all learn about coding and programming languages which will make it impossible for you to live up your dream if becoming an app developer.

To become an app developer you need to do B.Tech in Computer Science Engineering then only you will be able to learn all the things needed and with lots of hard work and determination you can become a successful app developer.

Feel free to ask if you have any more queries. All the best!!
