Best Books & Resources for CDAC CCAT 2026 Preparation

Choosing the right resources is crucial for effective CCAT preparation. Too many books and websites create confusion, while too few leave gaps in your knowledge. This guide provides the best resources for each subject, so you can focus on what matters.

Aptitude & Reasoning Books

Quantitative Aptitude — RS Aggarwal

The go-to book for aptitude preparation. Covers all topics asked in CCAT Section A with extensive practice problems.

  • Why this book: Comprehensive coverage, difficulty level matches CCAT
  • How to use: Focus on chapters relevant to CCAT — Percentage, Ratio, Time & Work, Probability

Alternative: Quantitative Aptitude — Arun Sharma

More strategy-focused with shortcut techniques. Good if you already know the basics and want to improve speed.

Reasoning — RS Aggarwal (Verbal & Non-Verbal Reasoning)

Covers seating arrangement, series, blood relations, syllogism, and all reasoning topics asked in CCAT.

Important: Pick only ONE aptitude book. Do not try to complete both RS Aggarwal and Arun Sharma. Master one book thoroughly. Practice the topics on Free Learning for CCAT-specific questions.

C Programming Books

Let Us C — Yashavant Kanetkar

The most recommended book for C programming in CCAT preparation. Covers all topics from basics to advanced concepts.

  • Key chapters: Pointers, Arrays, Functions, Structures, File Handling
  • How to use: Read each chapter and solve the exercises. Focus on output prediction questions.

For detailed topic breakdown, read our C Programming for CCAT guide.

Data Structures Books

Data Structures Using C — Reema Thareja

Excellent for understanding data structures concepts with C implementations.

  • Key chapters: Sorting, Searching, Linked Lists, Trees, Graphs
  • How to use: Focus on time complexity comparisons and algorithm steps rather than code implementation

See our Data Structures for CCAT guide for topic priorities.

Operating Systems & Other Books

Operating System Concepts — Galvin (Silberschatz)

The standard OS textbook. For CCAT, you only need specific chapters.

  • Focus on: Process scheduling (FCFS, SJF, Round Robin), Deadlock, Paging, Virtual Memory
  • Skip: Advanced topics like distributed systems, real-time OS

For OOP/C++ and Networking

These topics carry fewer questions (4-9 each). YouTube lectures and MCQ practice are sufficient — you do not need dedicated books.

  2. One practice platform for MCQs (Free Learning)
  3. One YouTube channel per subject (for concept clarity)
  4. One mock test series (Free Learning Mock Tests)
Completing one resource thoroughly is always better than partially reading five different books. Quality over quantity wins in CCAT preparation.
