IB 45 / 45 (predicted) Incoming Cambridge HSPS Tokyo · UK·US·HK

I hit a perfect 45 in the May 2023 session while studying at an international school in Tokyo. Now I have offers from Cambridge for HSPS along with HKU and HKUST. I know how it feels to stare at the Theory of Knowledge overlap and panic about the sheer volume of the syllabus.

Most students waste time highlighting textbooks. You need a targeted system to master the core themes quickly. I designed this six-week plan based on my own success. It focuses on high-yield arguments and clear structure so you can stop guessing what the examiners want.

Week 1: Re-Engage with Core Concepts & Definitions

The biggest mistake in Philosophy revision is jumping straight to essays without solidifying your foundational knowledge. Spend this week revisiting every core concept from your syllabus. For HL, this means a deep dive into your 'Texts and Traditions' – for me, it was Plato and Descartes. For SL, ensure you're crystal clear on ethical theories (utilitarianism, deontology, virtue ethics) and key epistemological debates.

Don't just re-read; actively define. Create flashcards for terms like 'a priori/a posteriori,' 'analytic/synthetic,' 'validity/soundness,' 'categorical imperative,' and 'hedonic calculus.' Understand the nuances. If you can't explain a concept in your own words to a five-year-old (or at least a slightly less philosophical friend), you don't truly understand it. This clarity will be your bedrock for constructing robust arguments later.

Week 2: Deconstruct Arguments & Identify Key Thinkers

Now that you know the 'what,' it's time for the 'how' and 'who.' For each topic, map out the main arguments and counter-arguments. Who are the primary proponents and critics? What are their key premises and conclusions? For instance, when studying the Problem of Evil, you should immediately think of Augustine, Aquinas, Hume, and Mackie, and be able to articulate their respective positions.

Create 'argument maps' or concise summaries for each major debate. For example, 'Utilitarianism: Mill (qualitative pleasures), Bentham (quantitative pleasures). Criticisms: Rights violations (Nozick's experience machine), demandingness, difficulty of calculation.' This structured approach helps you see the bigger picture and recall specific points under exam pressure. Focus on understanding the *logic* of their arguments, not just memorizing names.

Week 3: Master the Essay Structure (Paper 1 & 2)

IB Philosophy essays demand a specific structure: clear thesis, well-developed arguments, counter-arguments, and a nuanced conclusion. This week, practice outlining essays without writing full ones. Choose past paper questions for Paper 1 (e.g., 'To what extent is all knowledge ultimately based on experience?') and Paper 2 (e.g., a question on your chosen text).

For each outline, identify your thesis, three main points supporting it, a counter-argument for each, and how you'd refute or respond to those counter-arguments. Crucially, think about how you'll integrate examples and philosophical terminology. The goal is to demonstrate sophisticated understanding, not just regurgitation. Pay attention to the command terms: 'Analyse,' 'Evaluate,' 'Compare and Contrast.'

Week 4: Practice Writing Timed Essays & Source Analysis

This is where the rubber meets the road. Start writing timed essays. For Paper 1, aim for 45-60 minutes per essay. For Paper 2, dedicate the full 2 hours if you're doing HL (two essays) or 1 hour for SL (one essay). Don't worry about perfection; focus on completing a coherent argument under pressure. Use a timer and stick to it.

For HL students, Paper 3 (unseen text analysis) requires a different skill set. Practice reading philosophical texts you haven't seen before. Identify the author's main argument, their premises, and any assumptions. Then, critically evaluate it. What are its strengths? What are its weaknesses? Does it commit any fallacies? This isn't about agreeing or disagreeing, but about rigorous analytical engagement.

Week 5: Refine Arguments & Integrate Critiques

Review your timed essays. Where were your arguments weak? Did you sufficiently address counter-arguments? Did you use appropriate philosophical language? This week, focus on elevating your arguments from descriptive to analytical and evaluative. Instead of just stating a philosopher's view, *critique* it. For example, don't just say 'Bentham's utilitarianism focuses on pleasure'; rather, 'Bentham's quantitative approach to pleasure faces criticism for potentially justifying actions that violate individual rights, as seen in Nozick's thought experiments.'

Pay particular attention to the 'evaluation' aspect. A strong Philosophy essay doesn't just present arguments; it weighs their strengths and weaknesses, offers a nuanced judgment, and perhaps even suggests implications. This is often the difference between a 6 and a 7. Think about the 'so what?' of each argument you present.

Week 6: Final Review, Exam Strategy & Mental Preparation

The final week is for consolidating knowledge and honing your exam technique. Revisit your flashcards and argument maps. Practice quick outlines for a variety of past paper questions. Don't try to learn anything new; solidify what you already know. Ensure you understand the mark scheme criteria for each paper – what are examiners looking for?

Crucially, practice managing your time during the exam. Know how much time to allocate to planning, writing, and reviewing each essay. For Paper 3, practice quickly identifying the core argument and structuring your response. Get adequate sleep, eat well, and trust the preparation you've put in. Philosophy is as much about clear thinking under pressure as it is about knowledge.

Leveraging Resources: Teachers, Peers, and Past Papers

Your teacher is an invaluable resource. Don't hesitate to ask specific questions about concepts you find challenging or to get feedback on your essay outlines and timed responses. They know the syllabus and the marking criteria best. Utilise their office hours.

Collaborate with peers. Explaining a concept to someone else forces you to articulate it clearly and exposes gaps in your understanding. Discussing different interpretations of a text or argument can also broaden your perspective. Finally, past papers are essential, not just for practice but for understanding the types of questions asked and the depth of analysis expected. The IB website has a good archive; use it wisely.

Frequently asked questions

Is IB Philosophy SL or HL harder to get a 7 in?

While HL covers more content (especially the 'Texts and Traditions' component and Paper 3), the marking standards are proportionally higher for both. A 7 in SL requires the same depth of philosophical understanding and argumentative rigor for the topics covered as a 7 in HL does for its broader scope. The challenge is different, not necessarily 'harder' overall.

How important is memorizing philosopher names and dates?

Memorizing names and their core ideas is important for demonstrating knowledge. However, dates are less critical unless they're essential for contextualizing a specific historical argument (e.g., ancient vs. modern philosophy). Focus more on understanding *their arguments* and being able to accurately attribute them, rather than rote memorization of birth/death years.

What if I haven't read all the prescribed texts for HL Paper 2?

While reading the full texts is ideal, if time is short, focus on key sections and reliable secondary sources that summarize the main arguments and criticisms. For example, for Plato's Republic, ensure you understand the Allegory of the Cave, the Ship of State, and the tripartite soul, even if you haven't read every single book. Prioritize understanding the philosophical contributions over reading every word.

Can I use real-world examples in my essays?

Absolutely, and it's often encouraged! Real-world examples can strengthen your arguments by making abstract philosophical concepts more concrete and relatable. However, ensure they are relevant, well-explained, and directly support your philosophical point, rather than just being anecdotal. They should illustrate, not replace, philosophical reasoning.

How do I improve my critical thinking for Paper 3 (HL)?

Practice. Read opinion pieces, editorials, and even philosophical articles online. For each, identify the author's thesis, the evidence they provide, and any underlying assumptions. Look for logical fallacies. Then, formulate your own reasoned critique. The more you practice deconstructing arguments, the better you'll become at it under exam conditions. Focus on the *structure* of the argument, not just its conclusion.

The takeaway

Revising IB Philosophy in six weeks is entirely achievable with a structured, focused approach. Prioritize deep understanding of core concepts and arguments, master the specific essay structures required for each paper, and consistently practice timed writing and critical analysis. Leverage your teacher and peers, and don't underestimate the power of consistent, disciplined effort. This isn't about superficial learning, but about developing the philosophical muscle to articulate and defend nuanced arguments, which will serve you well beyond the IB exams.
