About Me

Hi. I am Teacher Benjamin. I am a very passionate teacher who uses real life examples in order to enhance understanding. I am a patient teacher who does not mind explaining concepts over and over again, using different approaches in order to enhance understanding. I have got experience in teaching chemistry and physics from beginners, through the intermediate phase all the way to high school. I enjoy the thrill that comes with assisting students to achieve their academic goals

Education

I am a holder of a Bachelor of Science (Honours) Chemistry which i obtained from the National University of Science and Technology in Zimbabwe. I also obtained a Bachelor of Technology from Unisa.

Experience / Qualifications

i have a total of 14 years experience in teaching Chemistry and Physics to beginners, intermediate and high school students, "O" Level and "A" Level students. I have helped countless students to achieve their academic goals, both online and physically.
Stoichiometry is a branch of chemistry that deals with the quantitative relationships that exist between the reactants and products in chemical reactions. I have designed the lessons in a systematic way that enhances understanding. You will learn how to calculate the amount of product that is going to be formed when you are given the amount of reactants and the yield. You will learn how to use balanced chemical equations and molar rations to figure out the excess and the limiting reactants. You will also learn how to calculate percentage purity of the reactants and percentage yield of a given chemical reaction.
Electricity is a division of physics that involves the flow of charges in a conductor. The three variables that are essential in electricity are voltage, electric current and resistance. I designed the lessons in a systematic way that enhances understanding. You will learn how apply Ohms law to calculate one variable given the other two. You will learn how to do electric circuit calculations that involve series, parallel and hybrid circuits.
Electrochemistry is a division of chemistry that involves using an electric current to bring about a chemical reaction or using a chemical reaction to bring about an electric current. I have designed the lessons in a systematic way that enhances understanding. You will learn the redox reactions involved and the oxidation and reduction half reactions involved. You will learn how reduction potentials and brought about and how they are used to calculate the emf of an electrochemical cell. You will learn the cell notation of galvanic cells and the different applications of electrolytic cells.

Mennatullah
Chemistry Educator | 5+ Years of Experience 🏆 | Expert in International & Local Curricula 🌍 | Nanoengineering Researcher 🇪🇬
As a chemistry teacher, I focus on using modern teaching methods that enhance the role of the student as an active element in the educational process. Since chemistry is a logical scientific branch, I use induction and deduction methods, in addition to brainstorming, and I make sure to include dialogue and discussion during lessons. As a researcher in nanoscience, I seek to develop students' creative and critical analysis skills, which helps them form their own opinions and ideas. I believe in the slogan of Egyptian scientists: “Because every mind makes a difference.” I also work to motivate students internally by stimulating the spirit of competition through educational competitions, games, oral and written tests, as well as practical experiments. I cannot ignore the fun side of chemistry, which is practical experiments. I make sure to apply these experiments as a researcher, whether through live explanation online or by preparing explanatory videos, whether produced by me or from reliable sources such as YouTube.

Chiwila
Specialized and Certified AS and A-Levels Tutor in Sequences and Series
I am a specialized and certified AS and A-Levels tutor with extensive experience in teaching Sequences and Series, along with a strong emphasis on Calculus. My tutoring sessions are designed to provide in-depth knowledge and understanding of these crucial mathematical topics, helping students to master the material and excel in their exams. Focus Areas in Sequences and Series Binomial Expansion: I guide students through the principles of binomial expansion, helping them understand how to expand expressions of the form (a+b)n . We explore the Binomial Theorem in detail, ensuring that students can apply it effectively in problem-solving scenarios. By the end of our sessions, students will be able to expand binomials with confidence and accuracy. Arithmetic Progressions (AP): Understanding arithmetic progressions is fundamental in mathematics. I provide comprehensive instruction on identifying and working with sequences where each term is derived by adding a constant. Students learn how to find the nth term, the sum of the first n terms, and how to apply these concepts to solve real-world problems. Geometric Progressions (GP): I also specialize in geometric progressions, where each term is obtained by multiplying the previous term by a constant. My approach includes explaining key concepts such as the nth term and the sum of a geometric series, both finite and infinite. We tackle a variety of problems to ensure a deep understanding of the subject. Further Sequences and Series: Beyond the basics, I explore further topics in sequences and series, including convergence and divergence. This advanced understanding prepares students for higher-level mathematics and the challenges they may face in university studies. Mastering Calculus In addition to Sequences and Series, I offer expert guidance in Calculus, which is essential for success in AS and A-Levels. My focus here includes: Differentiation: I help students understand the principles of differentiation, teaching them how to find derivatives and apply them to various functions. We work on techniques, such as the product and quotient rules, and explore applications of derivatives in real-world contexts. Integration: Students learn the fundamentals of integration, including definite and indefinite integrals. I emphasize techniques such as substitution and integration by parts, ensuring that students can tackle a wide range of problems. Application of Calculus: We explore how calculus is used in practical scenarios, including motion problems and areas under curves, to provide a holistic understanding of the subject. Proven Approach to Learning My proven approach focuses on solving past examination questions, which is crucial for familiarizing students with the exam format and types of questions they will encounter. I emphasize understanding core principles rather than rote memorization. This methodology not only boosts confidence but also ensures that students can apply their knowledge effectively in exams. I believe that personalized feedback is vital for growth. Throughout our sessions, I provide constructive feedback and support, allowing students to identify their strengths and areas for improvement. This continuous feedback loop fosters a growth mindset, empowering students to embrace challenges and develop resilience. Book Your Classes If you’re ready to elevate your understanding of Sequences, Series, and Calculus, I invite you to book your classes now. Experience the difference that comes with learning from an experienced tutor dedicated to your success. Let me guide you through an exciting and transformative learning journey that sets you on the path to achieving the highest grades possible. Together, we can unlock your full potential and ensure you are well-prepared for your AS and A-Level examinations. Your success is my priority, and I look forward to helping you reach your academic goals!
