Online IGCSE tutoring

I'm an A-Level and GCSE tutor in Physics, Chemistry, Biology and Accounting, with many years of experience teaching students one-to-one on platforms including Varsity Tutors and Wyzant, and privately. I hold a degree in Management Information Systems and an MBA with a specialization in Project Management, and I'm currently pursuing a PhD in Information Systems Management. I also studied English Literature and History at an advanced level, achieving top marks, which helps me teach students to write clear, well-structured exam answers.

Over the years I've worked with students from beginners through to exam preparation, and I tailor each lesson to the specification and exam style they are working toward, whether that's AQA, Edexcel, OCR or another board. My approach is simple and personal. I explain difficult topics in plain language with everyday examples, such as using a car journey to teach velocity, acceleration and graphs, so students understand why the methods work and not just how to use them. I teach step-by-step methods for calculations and exam questions, with past-paper-style practice and time management. Every lesson is built around the student's needs and learning style, so they understand the material and enjoy learning it.

Thanassis D had always seen learning as a map—layered, dynamic, and waiting to be explored. His studies in Computer Science and Earth Observation had sparked a lifelong pursuit: to bridge the technical with the human, the satellite with the classroom.

Each morning, he stepped into the American College of Greece not just as a teacher, but as a mentor within the International Baccalaureate (IB) program. His students didn’t just memorize code—they trained AI models, analyzed real-world datasets, and asked big questions. Under his guidance, classrooms transformed into innovation labs.

Thanassis D has more than six years of experience providing private tuition in Computer Science and Information Technology, including support for GCSE, IGCSE and A-Level students. He teaches core areas such as programming, algorithms, computational thinking, data structures, databases, computer systems, networking and data representation, with a strong emphasis on problem solving, exam preparation and developing students’ confidence with programming. He is comfortable adapting his teaching to different specifications and assessment formats.

By afternoon, Thanassis shifted roles, contributing to cutting-edge projects at the National Observatory of Athens. There, amidst servers and satellite feeds, he designed algorithms to predict floods, track wildfires, and model crop growth. His work wasn’t theoretical—it helped shape the response to real disasters across Europe.

Evenings often brought a different challenge: leading software architecture and engineering efforts at OpenGIS, where he helped build and scale QFieldCloud—a platform empowering geospatial scientists and NGOs worldwide. He balanced usability with scientific power, always pushing toward open, accessible Earth Observation tools.

In the summer of 2024, Thanassis co-designed and mentored at the IGARSS Summer School in Athens, welcoming students from around the globe. With warmth and clarity, he taught them how to turn noisy satellite data into environmental insight. His sessions were among the most remembered—where theory met purpose.

Beyond fieldwork and programming, Thanassis was a writer. His research papers explored the intersection of AI and remote sensing, published in reputable journals and presented at international conferences.

But perhaps his most heartfelt work was in education. He organized workshops on AI in Education, helping fellow teachers harness machine learning not as a buzzword, but as a meaningful classroom tool. In spring 2025, he led a school-wide professional development series for the entire American College of Greece, where educators from every department explored what it meant to teach in the age of algorithms.

Some knew him as a scientist, others as a teacher, a mentor, or a developer. But to everyone who crossed his path, Thanassis D was someone who believed in making knowledge practical—and empowering others to do the same.

Lina graduated from the University of Wollongong with both a BSc and MSc in Chemistry, achieving a High Distinction average. She began her career in the pharmaceutical industry, gaining valuable real-world experience before moving into education.

Since 2004, Lina has dedicated her career to teaching Chemistry and has over 20 years of experience teaching students aged 12–18 across international school curricula. She is currently the Head of Science and Head of Chemistry at a Singapore international school, where she leads the Science department and oversees a programme that combines Cambridge and Singapore curricula.

Lina’s strongest areas of expertise are Cambridge IGCSE, Cambridge O Level, Cambridge AS Level, and Cambridge A Level Chemistry. Her extensive classroom and leadership experience gives her a deep understanding of the syllabus content, assessment objectives, examination requirements, and question-answering techniques needed for students to succeed in Cambridge examinations.

In addition to her extensive Cambridge experience, Lina is highly qualified and experienced in teaching Pearson Edexcel Chemistry and Singapore-Cambridge O Level Chemistry, as well as IB Diploma Chemistry (HL/SL) and AP Chemistry. Her experience across multiple international curricula allows her to adapt her teaching to different examination boards while maintaining a strong focus on the specific requirements of each syllabus.

Over more than two decades of teaching, Lina has developed an extensive collection of exam-focused resources, past-paper materials, practice questions, and revision strategies. She understands that success in Chemistry requires more than knowing the content—students must also learn how to apply concepts, interpret questions, structure answers, and respond according to the expectations of their examination board.

Lina’s teaching philosophy is centred on helping students understand the “why behind the why” rather than relying on memorisation alone. Lessons typically begin by identifying gaps in prior knowledge, followed by clear explanations and modelling, guided practice, and independent problem-solving. Students are also given targeted practice to reinforce their learning between lessons.

Because Chemistry can be highly abstract, Lina uses visual explanations, analogies, worked examples, and real-world applications to make challenging concepts easier to understand. She creates a supportive learning environment where students feel comfortable asking questions, making mistakes, and developing confidence in their Chemistry abilities.

Whether a student is preparing for Cambridge IGCSE, Cambridge O Level, AS or A Level Chemistry, following the Singapore Chemistry curriculum, or studying Pearson Edexcel Chemistry, Lina combines deep subject knowledge, over two decades of international-school teaching experience, current academic leadership, and exam-focused teaching to help students reach their full potential.

Outside of teaching, Lina enjoys travelling and staying active through outdoor activities such as hiking, cycling, and jogging.
