Trusted teacher: I am a native Spanish speaker and a general language enthusiast. In addition to Spanish, I speak German and English. I am 100% confident that I will successfully teach you Spanish (while having fun and relaxing)! I've been teaching spanish for 15 years. I am 41 years old, graduated with honors from the University of Salamanca. My main goal in teaching is to make students feel relaxed and comfortable while studying. Do you already know Spanish? No problem! Rather than building the basics, we can design courses to suit your personal needs and preferences. We can write essays together, you can give presentations on topics that interest you or that I present to you, we can discuss current events, engage in debates, you can write summaries of newspaper articles, or we can delve into advanced grammar. Whatever you enjoy and need, we can do it together. All my courses combine speaking, listening and grammar practice in interaction with me. Unless you are a very advanced student, we work with learning materials created by some of the best language learning publishers in Germany. These materials serve as a common thread for our course, introducing new words, grammar and exercises at a good pace and in an interesting way, keeping you engaged and motivated. I also show you German food, music and places. In addition, I will introduce you to the best technological tools (homepages and applications) to boost your language learning and take it to the next level. Another important factor for me is the personal connection. We usually start our lessons with how the weekend or previous weekdays were like. Contact me now to arrange a first lesson in which we can get to know each other so that I can learn more about you, your needs and desires and thus design the optimal course for you.

Trusted teacher: All classes are given online. You will be provided with full methodology and an individual program will be generated for you to make sure you reach your goals. Philosophy is the foundation of all knowledge, the pursuit of truth through reason, and the key to understanding the world, human nature, and society. To study philosophy is to develop the ability to think critically, argue rigorously, and grasp the underlying principles that shape reality. Raised in a family devoted to intellectual discipline and excellence, I was immersed from an early age in classical philosophy, logic, ethics, metaphysics, and political thought. My approach is both historical and analytical, ensuring that students not only learn philosophical concepts but also develop the ability to question, debate, and apply philosophical reasoning to modern issues. A Rigorous Methodology for Mastering Philosophy: Understanding philosophy requires more than reading — it demands a structured approach to reasoning and analysis. I provide my students with a rigorous methodology that enables them to: -Analyze texts with precision, identifying key arguments and logical structures. -Construct well-formed philosophical arguments, mastering the art of reasoning and rhetoric. -Engage in dialectical thinking, refining their thoughts through structured discussion. -Write and express ideas with clarity and coherence, essential for academic and intellectual pursuits. A Dual Approach: The Great Thinkers & The Great Questions: History of Philosophy – The Evolution of Thought -Ancient Philosophy – Socrates, Plato, Aristotle, Stoicism, Epicureanism. -Medieval & Scholastic Philosophy – St. Augustine, St. Thomas Aquinas, Duns Scotus, Suarez. -Modern Philosophy – Descartes, Kant, Rousseau, Hegel, Nietzsche. -Contemporary Philosophy – Existentialism, phenomenology, political philosophy, ethics, metaphysics. Philosophical Themes – Mastering the Core Questions: -Metaphysics & Ontology – What is reality? What is existence? -Epistemology – How do we know what we know? What is truth? -Ethics & Moral Philosophy – What is good? What is justice? How should we live? -Political Philosophy – What is the best form of government? What is freedom? -Logic & Argumentation – Learning how to construct, deconstruct, and refine arguments. -Scholasticism – Mastering the structured reasoning of medieval philosophy, essential for theology and metaphysics. - Languages and societal questions. A Course Designed for Your Needs Whether you seek to explore philosophy for personal enrichment or academic excellence, this program is tailored to your level and goals: -Academic support (school, high school, university) Essay & debate preparation -Personal enrichment (deepening your understanding of the great ideas) -Diplomatic, political, or legal insight (for those in governance, law, or international relations) Philosophy is not just an intellectual exercise—it is a way of seeing the world, questioning assumptions, and refining thought. With my structured methodology, you will gain the ability to navigate complex ideas with precision and confidence. Join me, and develop a mind that is sharp, informed, and ready to engage with the deepest questions of life, to find the truth and, most important, to understand why it is true and how to act upon it.

Trusted teacher: Hello, psychophiles! 👋 My name is Despoina, and I’m of Greek origin. Friends and family call me Debbie, so that’s how you’re going to call me too! 😊 I hold a degree in psychology and am a licensed professional in Greece, currently pursuing my MSc in Health Psychology! I may have limited tutoring experience, but what I bring to the table is my limitless passion for psychology. My strong academic background, participation in several seminars (depression and psychotherapy, analytic group psychotherapy, somatic illnesses, etc.), as well as my internships (A21, Center for Talented Youth – CTY), have allowed me to explore psychology in greater depth and gain hands-on experience and valuable knowledge. Are you curious about why people think, feel, and behave the way they do? Welcome to Unlocking the Mind, an engaging and thought-provoking psychology course designed for students (and not only!) eager to explore the depths of human behavior. Psychology isn’t just a subject—it’s a window into understanding ourselves and the world around us. In this course, we’ll dive into various branches of psychology, from cognitive and behavioral to clinical and social, uncovering the fascinating mechanisms behind emotions, decision-making, memory, and personality. But this isn’t your average lecture-style class! Expect dynamic discussions, real-world applications, and an interactive learning experience featuring educational videos, movie analyses, and thought-provoking case studies. I’ll also recommend must-read books to deepen your understanding of the field. Whether you’re new to psychology or looking to expand your knowledge, this course will challenge your thinking and provide you with invaluable insights into the human mind. Classes will be tailored to your needs, ensuring a personalized and enriching experience. In addition to the core topics, I’m also happy to assist with exam preparation, psychology assignments, or simply answer any questions you have about the field. If you love discussing psychology as much as I do, let’s dive into engaging conversations and explore the subject together! Let’s explore the science of psychology together—because understanding the mind is the key to unlocking endless possibilities! 🧠📝💡✨

Dean
Our first lesson with Dean was productive and an eye-opener. The lesson made me realize there are a few critical areas that I needed to grasp and understand to articulate the IELTS exam preparation. The lesson was fun, and Dean is a good attention detail tutor; he takes time to give a clear explanation of what to focus on. His energy is amicable, and he takes his work seriously. Thank you for the first lesson, and we look forward to our following lessons.
