About CS Engineering Gyan
A learning platform for Computer Science and IT students, with free written tutorials, video lessons and optional handwritten revision notes.
CS Engineering Gyan (csegyan.com) is an educational website for students of Computer Science and Information Technology. It started with free video lessons on YouTube and grew into a website of written tutorials organised subject by subject.
Each tutorial chapter explains a topic step by step, with examples, tables, diagrams and practice questions, for subjects such as Data Structures, DBMS, Operating Systems, Computer Networks, Software Engineering and programming languages. All of these tutorials are free to read.
For students who want a short, hand-written version for last-minute revision, we also offer optional handwritten notes at a low price. Buying them is never required to use the tutorials.
