Our last one is actually a fun fact: did you know that Lanterna started out as a CAS project in 2002? A group of older IB students decided to support younger students with their academic performance – everything from helping out with homework to teaching whole topics that students had missed or not understood. So we’re living proof that CAS is totally worth it in the end!

Lanterna Team
We’re the Lanterna Team — a group of 600+ IB expert tutors, ranging from 45/45 IB graduates to IB teachers with 30+ years of teaching and examiner experience.

For over 20 years, we’ve supported tens of thousands IB students worldwide with one clear focus: making high achievement feel more doable. Our team of experienced tutors have come together to combine their deep curriculum knowledge with practical strategies that are proven to work.

Whether you’re building strong foundations in DP1, pushing for a final stretch in DP2, or looking for clarity on what to prioritise, we’re here to help you study smarter, stay confident, and get results.

Creativity, Activity, Service (CAS) is one of the three core components of the IB Diploma Programme. It encourages students to engage in a range of experiences alongside their academic studies, fostering personal and interpersonal development through real-world learning. It's an opportunity to explore interests, contribute to the community, and reflect on personal growth, making the IB experience more holistic and enjoyable.

The key is to choose activities you genuinely enjoy and that align with your interests. CAS shouldn't feel like extra homework; it's a chance to have fun, try new things, and balance your academic workload with enriching experiences. This guide provides many "easy" ideas to get you started, focusing on activities you'll love!

Yes, surprisingly, certain video game activities can count for CAS, particularly under Creativity, if they involve design, storytelling, or critical problem-solving with a reflective component. It's all about how you engage with the activity, what you learn, and how you reflect on your personal growth and outcomes.

Reflection is a crucial part of CAS, demonstrating your learning and development. It involves thinking critically about what you learned, how you developed new skills, and the impact of your actions. Our expert tutors can guide you on how to structure meaningful reflections that clearly articulate your growth and demonstrate achievement of the CAS learning outcomes.

Absolutely! While this guide provides many ideas, our expert IB tutors and Student Success Experts can offer personalised guidance. They can help you brainstorm activities that fit your interests, ensure they meet IB requirements, and even help structure your CAS project for maximum impact and enjoyment. Beyond CAS, our 600+ tutors provide support across all IB subjects and core components like IAs, EEs, and TOK.

The Lanterna IB consultation is a free, no-pressure 20-30 minute session with an IB Student Success Expert. It's designed to help you get clarity on your IB journey, whether you're a student or a parent, and walk away with a personalised plan for what to focus on now.

Yes, the consultation is completely free, and there is absolutely no obligation to book tutoring afterwards. Our goal is to provide valuable guidance and a clear plan for your next steps, backed by our team's extensive IB experience, with zero pressure to commit to anything further.

Our Student Success Experts are highly experienced professionals with deep knowledge of the IB Diploma Programme. They've supported thousands of IB students and families, offering insights, strategic advice, and helping to identify the best path forward for academic success and personal growth. They're here to help you navigate the IB with confidence.

Lanterna's tutors are all high-achieving IB graduates (many with 40+ points), experienced IB teachers, or examiners. They provide personalised, one-on-one online tuition across all IB subjects at both SL and HL. They can help with everything from understanding complex concepts and exam preparation to refining IAs, EEs, and TOK essays, ensuring you develop the skills and confidence to excel.

Yes, absolutely. Our Student Success Experts can help you build a tailored study plan during your free consultation, identifying your priorities and outlining effective strategies. If you choose to work with a tutor, they will further refine this plan, providing ongoing support to ensure you stay on track and achieve your academic goals across all your IB subjects and components.
