CAS Tips

CAS and TOK are an essential part of the IB experience. From choosing meaningful CAS experiences to developing stronger TOK arguments, here is some advice from our tutors who have been in your shoes!

Our answers to your CAS questions

How do I choose a good CAS activity?

You don’t always need to start something completely new for CAS. Think about something you already enjoy or are passionate about, and turn it into a CAS Project. With some extra planning, collaboration and reflection, an activity you already love could become a meaningful CAS experience.

What should I actually write in a CAS reflection?

Don’t just describe what you did but try to reflect on what you learned, how you felt, what challenged you and how you changed. A strong reflection shows your personal growth and connects your experience to the CAS learning outcomes.

Try asking yourself:

  • What did I learn from this experience?
  • What challenged me, and how did I respond?
  • What would I do differently next time?
  • How did this experience change my perspective?

Tutor Tip: CAS reflections should tell the story of your growth, not just the story of what happened.

What counts as Creativity, Activity and Service?

The three CAS strands are all about developing different aspects of yourself:

Creativity: Exploring ideas and expressing yourself through creative or artistic activities. Think: photography, music, writing, cooking or learning an instrument.
Activity: Taking part in physical activities that contribute to a healthy lifestyle. Think: football, running, swimming, dancing or hiking.
Service: Using your time and skills to make a positive difference to others or your community. Think: volunteering, tutoring, fundraising or community projects.

Tutor Tip: Your CAS experiences don’t have to fit neatly into just one strand. A single project can combine Creativity, Activity and Service!

How is a CAS Project different from a normal CAS experience?

A CAS experience is usually a single activity or a shorter-term experience, while a CAS Project is a more sustained experience that involves planning, collaboration and multiple stages.

For example, volunteering at a local charity for a day could be a CAS experience. Organising a fundraising campaign with your classmates over several weeks would be a CAS Project.

Tutor Tip: Think of a CAS Project as taking an idea, planning it, working on it with others and seeing it through to the end.

Ways to combine Creativity, Action & Service

One tutor's CAS project involved finding a school in the remote areas of the country where community outreach was needed. The students hiked to planted trees (Activity), taught the students how to paint (Creativity) and raised money to build a school cafeteria (Service).

Theory of Knowledge

TOK Tips

CAS and TOK are an essential part of the IB experience. From choosing meaningful CAS experiences to developing stronger TOK arguments, here is some advice from our tutors who have been in your shoes!

Our answers to your TOK questions

How is TOK different from my other IB subjects?

In most IB subjects, you learn and apply knowledge. TOK asks you to step back and question that knowledge; How we know something, why we believe it, and whether we can be certain.

Tutor Tip: Don’t just ask “What do I know?” Ask “How do I know?”

What is a claim and a counterclaim?

A claim is an argument or position that answers the TOK question. A counterclaim challenges, questions or provides an alternative perspective to that claim.

For example, consider the idea: “Technology makes knowledge more reliable.”

Claim: Technology can make knowledge more reliable because it allows us to collect, store and analyse large amounts of data with greater accuracy.

Counterclaim: However, technology can also make knowledge less reliable when algorithms contain biases or when misinformation spreads rapidly online.

The goal isn’t to simply say “the opposite is true.” A strong counterclaim adds nuance to your argument by showing that the issue can be viewed from another perspective.

Tutor Tip: After making a claim, ask yourself: “Under what circumstances might this not be true?” That question can help you develop a meaningful counterclaim.

How do I make my TOK essay more analytical?

Don’t just explain what happened but explore why it matters. After making a point or giving an example, ask yourself: “So what?” and “What does this tell us about how knowledge works?”

Tutor Tip: Always go one step beyond describing your example and explain what it reveals about knowledge.

What makes a good real-life example?

A great opportunity to explain that specific, relevant and well-explained examples are much stronger than simply dropping famous names or events into an essay.

Tutor tip: Don’t just mention an event or person but rather, explain how it supports, challenges or adds nuance to your claim.

Extended Essay

Extended Essay Tips

DP1: Getting Started with Your Extended Essay

1. Follow your curiosity. Choose a subject and topic that genuinely interests you. You'll spend months exploring it, so pick something you want to understand more deeply.

2. Start with a question, not just a topic. Instead of choosing a broad area, think about a specific issue you want to investigate. Your research question will guide your entire essay.

3. Explore your sources early. Before committing to a topic, check that enough reliable research, data, or primary sources are available to support your investigation.

4. Keep your scope manageable. The 4,000-word limit means you can't cover everything. Focus on a question that allows for detailed analysis rather than a broad overview.

5. Build good research habits from day one. Keep track of your sources, take organised notes, and record useful references as you go. Future you will thank you for not needing to re-research sources all over again!

DP2: Refining Your Extended Essay

1. Revisit your research question. Does your essay consistently answer the question you set out to investigate? Refine your argument if your research has revealed a more focused direction.

2. Prioritise analysis over description. Don't just explain what your sources say. Evaluate the evidence, compare perspectives, and show how your findings support your argument.

3. Challenge your own argument. Consider alternative explanations, conflicting evidence, and the limitations of your research. Acknowledging these can strengthen your analysis.

4. Check that every paragraph has a purpose. Each section should contribute to answering your research question. Remove repetition and information that doesn't support your central argument.

5. Polish your academic writing. Check that your structure flows logically, your citations are consistent, and your conclusion directly answers your research question without introducing new arguments.

6. Use feedback strategically. Identify recurring issues in your supervisor's feedback and prioritise changes that improve the quality of your research, analysis, and argument.
