- CPU, memory, and storage
- Networks
- Types of networks (LAN, WAN, PAN)
- Network topologies and protocols (TCP/IP, HTTP, FTP)
- OSI and TCP/IP models
- Databases
- Database concepts and structures (tables, keys, relationships)
- SQL basics (SELECT, INSERT, UPDATE, DELETE)
- Database management systems (DBMS)
Resources:
- Textbook chapters on computer fundamentals, networks, and databases.
- Online tutorials and crash courses (e.g., Khan Academy, Codecademy).
Day 2: Advanced Topics and Computational Thinking
Focus: Machine Learning, Computational Thinking, and Case Study Preparation
- Machine Learning
- Basic concepts (supervised vs. unsupervised learning)
- Algorithms (decision trees, neural networks)
- Practical applications
- Computational Thinking
- Problem-solving strategies (abstraction, decomposition, pattern recognition)
- Algorithm design and analysis
- Case Study
- Review the case study provided by the IB.
- Identify key issues, technologies, and potential solutions.
Resources:
- Online courses (e.g., Coursera, edX) for machine learning basics.
- IB-provided case study materials and sample case studies.
Day 3: Programming and Practice
Focus: Programming and Hands-on Practice
- Programming
- Basics of programming languages (Python, Java)
- Control structures (loops, conditionals)
- Functions, arrays, and data structures
- Hands-on Practice:
- Solve programming challenges on platforms like HackerRank or LeetCode.
- Work on small projects or exercises to reinforce learning.
Resources:
- Online coding platforms (HackerRank, LeetCode, Codecademy).
- Textbook exercises and programming practice problems.
Day 4: Object-Oriented Programming (OOP)
Focus: OOP Concepts and Applications
Object-Oriented Programming

Day 5: Abstract Data Types (HL Only) and Review
Focus: Abstract Data Types (HL) and Comprehensive Review
- Abstract Data Types
- Stacks, queues, linked lists, trees, graphs
- Implementing and using these data structures
- Comprehensive Review:
- Review notes and key concepts from previous days.
- Focus on weak areas identified during practice.
Resources:
- Textbook sections on abstract data types.
- Review sessions and summary notes.
Day 6, 7: Mock Exams and Final Review
Focus: Mock Exams and Final Touches
- Mock Exams:
- Take full-length practice exams under timed conditions.
- Focus on Papers 1, 2, and 3 (HL only).
- Final Review:
- Review incorrect answers and understand mistakes.
- Go over key concepts one last time.
Resources:
- Revision notes and summaries.
