How to revise IT

1. Master the 6 Topic Areas (TA)

The exam covers these specific sections. You must be able to define, describe, and apply them to scenarios:

• TA1: Design Tools: Know how to create and explain Mind Maps, Flowcharts, Visualisation Diagrams, and Wireframes.

• TA2: Human Computer Interface (HCI): Understand how we interact with systems (Touch, Voice, Gesture) and hardware considerations like screen size or processing power.

• TA3: Data & Testing: The difference between Data (raw facts) and Information (processed data). Focus on Validation (computer check) vs. Verification (human check).

• TA4: Cyber-security & Legislation: Understand threats like Phishing, Ransomware, and DDoS, plus the laws (GDPR, Computer Misuse Act).

• TA5: Digital Communications: Types of networks (LAN, WAN, PAN) and how we share data (Email, Cloud, Social Media).

• TA6: Internet of Everything (IoE): How everyday objects (Smart Fridges, Wearables) connect to the internet to make life easier.

2. Practice "The Big Create" (8-Mark Question)

One question will always ask you to create a design tool based on a scenario.

The Skill: You might be asked to draw a Wireframe for a mobile app or a Flowchart for a login process.

Pro Tip: Use a pencil! If you realize your flowchart logic is wrong halfway through, you need to be able to rub it out. Label everything clearly to show the "User Journey."

3. The 9-Mark "Discuss" Question

This is the "Extended Response" at the end of the paper. It usually asks you to look at the impact of a technology (like the IoE or Cloud Storage) on a business or individuals.

Structure: Don't just write a wall of text. Use a "Balanced Argument":

Paragraph 1: Benefits (e.g., "It improves efficiency because...")

Paragraph 2: Drawbacks (e.g., "However, it increases security risks such as...")

Paragraph 3: Conclusion (e.g., "Overall, for this specific company, the benefits outweigh the risks because...")

4. Exam Technique: Decoding the Command Words

OCR is very specific about how you answer.

E.g. 

• Identify / State

  • 1 mark

  • Just give the name (e.g., "Firewall"). 

• Describe

  • 2+ marks

  • Give the "What" and the "How/Why" (e.g., "A firewall monitors traffic to block unauthorized access.")

• Explain

  • 3+ marks. 

  • You need a "Point, Evidence, Explain" chain. Link it back to the Scenario provided in the question.
