I’m a passionate physical science teacher with over six years of classroom experience and a strong presence on online tutoring platforms. I absolutely love what I do, and I care deeply about my student’s success. My classes are highly engaging, interactive, and tailored to each learner’s needs. I specialize in breaking down complex scientific concepts into simple, step-by-step explanations that make learning easier and more enjoyable. Nothing makes me happier than seeing my students have those “aha!” moments. If you're looking for a tutor who’s patient, dedicated, and makes science fun and understandable, I’d love to work with you. Let’s make learning science exciting together! I hold a Bachelor of Science in Geology and an Honors degree in Geology, both obtained from the University of Limpopo. I later pursued my passion for teaching by earning a Postgraduate Certificate in Education (PGCE) from the University of Witwatersrand. In addition to my academic qualifications, I also hold certificates in Computer Studies as well as Business and Entrepreneurship, which have equipped me with valuable skills beyond the classroom. My diverse educational background allows me to connect scientific knowledge with real-world applications, and it strengthens my ability to deliver engaging, well-rounded lessons to my students.

English I am studying mathematics with a minor in physics at the Technical University of Berlin and have only a few exams left before completing my degree. I hold the Goethe Certificate C2, the highest language diploma of the Goethe Institut, and I also teach several other languages: English, French, Spanish, Italian and Romanian. My teaching style is guided by discipline, strategic thinking and analytical precision, supported by my chess background, which helps me approach complex situations with calmness and clarity. Upon request I can provide both my language certificates and the confirmation of my bachelor studies at the Technical University of Berlin in Germany. Français Je poursuis des études de mathématiques avec une spécialisation secondaire en physique à l’Université technique de Berlin où il ne me reste que quelques examens avant la fin du cursus. J’ai obtenu le Goethe Zertifikat C2, le plus haut diplôme linguistique de l’Institut Goethe, et j’enseigne également plusieurs autres langues: anglais, français, espagnol, italien et roumain. Mon enseignement repose sur la discipline, la réflexion stratégique et la précision analytique, soutenues par mon expérience aux échecs qui m’aide à aborder les situations complexes avec calme et clarté. Je peux sur demande présenter mes certificats de langue ainsi que la confirmation de mes études de licence à l’Université technique de Berlin en Allemagne.

My name is Elena Rhei. I’m a Bachelor of Science in Nursing graduate and a TEFL-certified English teacher with over 11 years of experience teaching students from various countries and age groups. I love helping learners improve their overall English communication skills. My classes focus on both language accuracy and real-life fluency. Seeing my students grow and achieve their goals has been the most rewarding part of my career. In my leisure time, I enjoy watching movies, listening to the radio, dining in fancy restaurants, and going on road trips. I graduated with a Bachelor’s degree in Nursing and am a TEFL-certified English teacher. My studies provided a strong foundation in both health and education, as we were exposed to patients in various communities where we were expected to provide knowledge and health education. This experience taught me how to effectively engage students from diverse backgrounds and encourage them to improve their skills with confidence.

My name is Mark Sean A. Manubag, and I hold a degree in Chemistry. For the past two years, I’ve been teaching and tutoring high school and college students, mainly in math, chemistry, and physics. I love making complex topics feel simple and approachable for learners at different levels. As a teacher, I am patient, supportive, and goal-oriented. I believe in guiding students step by step until they feel confident in themselves. One of my strengths is breaking down difficult concepts into clear, relatable ideas. Seeing students progress—from struggling on quizzes to celebrating their own achievements—is what inspires me to teach. My teaching style is interactive and student-centered. I enjoy connecting lessons to real-life examples, whether through cooking, music, or everyday situations, so that learning feels both meaningful and fun. I’ve found that when students can relate to a topic, they learn faster and remember it longer. Outside the classroom, I enjoy reading, exploring different genres of music, and learning languages. At the moment, I’m studying Italian, which helps me stay in touch with the challenges of being a learner myself. That perspective allows me to connect more deeply with my students and encourage them to see learning as a lifelong skill. Teaching, for me, is about helping students discover their own potential. I want my learners to not only improve their grades but also develop the confidence and curiosity that will benefit them well beyond the classroom. I graduated with a Bachelor of Science in Chemistry. During my studies, I gained extensive training in laboratory instrumentation, including GCMS, FTIR, AAS, and UV-Vis, and completed internships with the Food and Drug Administration of the Philippines, the Department of Agriculture – Bureau of Fisheries and Aquatic Resources, and the Philippine–Japan Active Carbon Corporation. My undergraduate thesis focused on the spectrophotometric determination of phenolics from plant extracts, which strengthened my background in analytical chemistry. After graduation, I successfully passed the Philippine Licensure Examination for Chemists in September 2014. Alongside my academic journey, I began working as a freelance tutor between 2012 and 2014, supporting high school and college students in mathematics, chemistry, and other sciences. Many of the students I taught came from institutions with advanced science and math programs, while others needed help building foundational understanding. Through one-on-one lessons, I developed a teaching approach that emphasized patience, step-by-step guidance, and real-life applications, helping students not only grasp concepts but also build confidence in their own abilities. This tutoring experience deepened my passion for education and showed me the impact of making complex topics simple and engaging. I take pride in seeing students’ progress—from struggling on exams to achieving strong results. Teaching continues to be a meaningful part of my career, complementing my professional work as a chemist by allowing me to share knowledge and inspire curiosity in the sciences.
