Mathematics (Applied Math, Calculus, Linear Algebra, Geometry, IBM Exams, Entrance Exams): Primary/High School/Bachelor/Master StudentsMathematics is all about learning basic elements with which you can create explosions, interactions and much more desired computations. It is the heart of every science known and without it, even the text that I am writing right now would not work (recall binary numbers).
I have always been passionate about Math and during primary and high school I attended many Regional Math Olympiads where I usually won the top 5 places. During this period, I got the chance to be trained by university professors and gained knowledge of many complex math concepts at a really young age. This made it possible for me to afterward be able to explain these concepts in a brief and clear manner to my fellow students. I aspire to visualize everything with everyday life and when students see this connection, the puzzle is finally solved. We can cover all of the branches of mathematics together at the desired level and degree level. Starting from Algebra, Geometry, Calculus, Probability, Trigonometry and much more, we will build that mathematic intuition in no time!

Chiwila
Specialized and Certified AS and A-Levels Tutor in Sequences and SeriesI 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.

MATHS lessons for IB, pre IB, MYP, IGCSE, and GCSE studentsI have worked for 5 years now with kids from international schools who were "hating" maths because the methods used by their IB teachers were too complicated and hard to understand.
I believe that no one is "not mathematical", we just have to find the way to approach the subject together; I have indeed a few teaching methods that can be adapted to a kids' needs, I believe every kid needs a different method to fully understand the subject.
I provide 3 types of lessons that represent 3 phases:
1. THEORY - Understanding the theory behind the exercises, this phase is the shortest since I believe that to fully understand maths you need to exercise.
2. EXERCISES - Doing exercises divided by subject we. just went through in the theory part.
3. PAST PAPERS - Going through past papers to "simulate" a potential exam.
Dividing the process in 3 phases has proven really effective in succeeding not only during the year but also at the final exams.
