CSE Pro is the complete, unlocked, ad free edition of our Computer Science Engineering course. Every one of the 400+ tutorials is included, with nothing gated and nothing hidden behind a second purchase.
ONE PAYMENT, EVERYTHING UNLOCKED
No subscription. No recurring charge. No advertisements between lessons. Pay once and the full computer science and engineering syllabus is yours.
WHAT IS INCLUDED
Data structures and algorithms, including arrays, linked lists, trees, graphs, sorting, searching, dynamic programming and complexity analysis.
Database management systems, including SQL, normalization, ER modelling, transactions and indexing.
Operating systems, including process scheduling, deadlocks, memory management, virtual memory and file systems.
Computer networks, including the OSI and TCP/IP models, routing, subnetting and network security fundamentals.
Computer architecture, including pipelining, cache design and memory hierarchy.
Programming fundamentals with examples in C, C++, Java and Python, plus object oriented programming.
Software engineering, theory of computation and compiler design.
BUILT FOR EXAM AND INTERVIEW PREPARATION
Distraction free reading with no advertisements, which matters when you are working through a difficult topic and cannot afford to be pulled out of it.
Full text search across the entire syllabus, so you can find a definition or an algorithm in seconds during revision.
Short, self contained lessons that fit into the gaps in a study day.
Bookmarks and resume, so a long revision session survives being interrupted.
WHO BUYS THE PRO EDITION
Students in the final weeks before semester or university examinations who want the whole syllabus available without limits.
Candidates preparing for competitive technical examinations and campus placement interviews.
Working developers refreshing computer science fundamentals before interviewing, who would rather pay once than sit through advertisements.
Anyone who studies on unreliable or expensive mobile data and wants their material to stay available.
HOW THIS DIFFERS FROM THE FREE EDITION
The free edition gives you a large sample of the course with advertisements. CSE Pro removes every restriction and every advertisement, permanently, for a single payment. If you have already been studying with the free edition, your progress and reading habits carry straight over.
WHY FUNDAMENTALS ARE WORTH PAYING FOR
Programming languages and frameworks turn over constantly. Data structures, algorithms, operating systems and networking do not. These are the topics that technical interviews are still built on and that separate engineers who can reason about a hard bug from those who cannot.
Buy once. Study for years. No subscription, no upsell, no advertisements.
