There are no strict prerequisites for learning Linux after 12th, which makes it a great choice for students interested in IT, cybersecurity, or software development. However, having some basic skills and knowledge can help you get started more easily:

✅ 1. Basic Computer Knowledge

You should be comfortable using a computer—navigating folders, copying files, and installing software.

✅ 2. Understanding of Operating Systems

A basic idea of what an operating system does (like Windows) helps you understand Linux concepts more quickly.

✅ 3. Basic English Reading Skills

Since most Linux commands and manuals are in English, understanding basic instructions is important.

✅ 4. Interest in Technology

Curiosity about how computers work, how systems are managed, or how hackers operate can motivate learning Linux deeply.
