CSE Pro is the complete, unlocked, ad free edition of our Computer Science Engineering course. 84 subjects, 425 tutorials, 8,891 lessons and 26,874 practice questions — everything included, nothing gated, nothing behind a second purchase. ONE PAYMENT, EVERYTHING UNLOCKED No subscription. No recurring charge. No advertisements between lessons. Pay once and the full syllabus is yours, online and offline. WHAT IS INCLUDED Data structures and algorithms — arrays, linked lists, trees, graphs, sorting, searching, dynamic programming and complexity analysis. Database management systems — SQL, normalization, ER modelling, transactions and indexing. Operating systems — process scheduling, deadlocks, memory management, virtual memory and file systems. Computer networks — OSI and TCP/IP models, routing, subnetting and network security fundamentals. Computer architecture — 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. 26,874 PRACTICE QUESTIONS Every subject has its own question bank. Sessions are ten questions, four options each, drawn from the chapter you have been reading. Three timed difficulty levels: beginner 30 seconds per question, intermediate 20, expert 10. Pass at 70%. Filter by difficulty, by attempted or untried, and by your best score, so revision goes straight to your weakest subjects. Full attempt history, kept permanently, so you can see progress across a whole exam season. INTERVIEW PREPARATION INCLUDED 25 technical interview roles, 100 questions each, 2,500 in total, built around what campus placements and technical interviews actually ask. Timed, scored and saved like every other session. FULL OFFLINE STUDY Download any subject and read it with no connection at all. Lesson text lives on the device. The Downloads screen shows what is stored, how much space it takes, and lets you cancel, resume or clear any subject. Anything you open is cached automatically. This matters exactly when it matters most: the night before an exam, on unreliable campus wifi, or on expensive mobile data. PROGRESS AND CERTIFICATES Mark lessons complete and track a real completion percentage per subject. The Continue card returns you to the exact lesson you left. Keep a daily study streak, with an optional reminder that stays off unless you turn it on. Finish every lesson in a subject and pass its quiz at 70% or above to unlock a certificate you can save and share. BUILT FOR EXAM AND INTERVIEW PREPARATION Distraction free reading with no advertisements, which matters when you are working through a difficult topic. Full text search across the entire syllabus. Syntax highlighted code with one tap copy. Bookmarks and history. Light, dark and system themes, adjustable font size, navigation placement options and proper tablet layouts. WHO BUYS THE PRO EDITION Students in the final weeks before examinations who want the whole syllabus and question bank with no limits. Candidates preparing for competitive technical examinations and campus placements. Working developers refreshing fundamentals before interviewing, who would rather pay once than sit through advertisements. Anyone studying on unreliable or expensive mobile data. HOW THIS DIFFERS FROM THE FREE EDITION CSE Pro removes every restriction and every advertisement, permanently, for a single payment. Programming languages and frameworks turn over constantly. Data structures, algorithms, operating systems and networking do not. Buy once, study for years. No subscription, no upsell, no advertisements. Questions, corrections or a topic request?
