Chemical Calculations for AS & A2 Chemistry (All Exam Boards)

Von 29.63 € /Std

Calculations are a necessary and fundamental element (pun intended) of Advanced and University Level Chemistry and it is best to be well-acquainted with the requisite formulae and equations prior to starting your AS studies as it can become rather messy! It also seems to be the topic most students find challenging.

All UK Exam Boards examine an almost identical application of the calculations required to meet the syllabuses. The calculations demonstrated in A2 are an extension to what is established during AS; the content may be more comprehensive in A2 but the general application is not dissimilar.

To obtain the most from this class students should be familiar with CGP’s Complete Course (relative to their exam board, e.g. AQA, OCR, ... ) [AS or A2 edition]- in particular, the chapters outlining chemical calculations.

If you’ve ever felt that science and math are difficult, it’s probably because no one showed you how to think like a problem solver.
In my classes, you’ll learn not just formulas or code but how to truly understand concepts, apply them, and build strong logical intuition.

I teach:
• 🔢 Mathematics: From algebra and calculus to applied problem-solving for real-world use.
• 💻 Computer Science: Coding fundamentals (Python, C++), algorithms, and logical thinking for beginners and intermediate learners.
• ⚛️ Physics: Mechanics, thermodynamics, and practical examples that make abstract ideas simple and visual.

As a Software Engineer and Master’s student in Engineering at Nagoya University, I bring both academic knowledge and hands-on experience from real projects. My teaching approach is interactive, visual, and deeply focused on understanding over memorization.

Let’s turn complex problems into clear, step-by-step insights — and make learning something you genuinely enjoy.

You are a university student and have trouble with your math courses? Don't fret, I'm here to help! It doesn't matter whether you are a math student or from a different major, whether you are from an applied background or struggle with pure maths - the lessons will only cover what you need. Mathematics has a lot to do with practice and getting familiar with the way of thinking logically. With my help and guidance, I am sure you will become confident in solving problems and understanding mathematical concepts.

The lessons will be tailored to your needs and their structure depends highly on you: usually it is a mixture of repeating the content, solving exercises together, summarising important concepts and talking about exercises you tried yourself at home. The topics, content, pace and methods of learning will be adjusted to your needs, ensuring that you get the most out of my lessons. Besides the lessons, you will get "homework" to work on to strengthen your skills and independent working.

Topics include, but are not limited to:
-Trigonometry
-Geometry
-Linear Algebra
-Calculus (limits, derivation, Integration, etc.)
-Set Theory and Metrics
-Analysis (functions, Taylor series, etc.)
-Algebra (Group/Ring/Field theory, Galois theory, etc.)
-Number Theory (sequence and series)
-Probability (statistics, stochastic processes, etc.)
-Logic and Proofs
-Numerical Analysis
-(Algebraic) Topology (Homology theory, etc.)

If you have another topic in mind that you really need help with, just send me a message!

Whether you need someone that explains the concepts to you or just someone to practice exercises with - I am sure I can help you. You have an exam soon and want to review the main topics? No problem! You have a very specific problem, question or topic that you need help with? I'm here to answer any questions!

The most important part of my lessons is, however, to ensure a safe and comfortable environment - I have no issue with explaining the same concept over and over again until I am convinced that you have understood it. It is important to me that you feel comfortable in asking any questions - I want to show you, that Math is more than a subject and that it can be fun!

Mathematics is a very beautiful subject but students often struggle understanding the concepts. In maths, every thing is about how we approach the problem and our perspective for solving it. Every teacher has their own qualities but mine is to make maths fun and easy to understand. I’m a very friendly and fun teacher.

Mathematics and Physics are foundational subjects that develop logical thinking, problem-solving skills, and a deep understanding of how the world works. However, students often feel overwhelmed by abstract concepts, formulas, and problem sets when they are not explained clearly or applied correctly.
I’ve designed this course as a practical and structured guide to Mathematics and Physics, specifically aimed at helping students truly understand the concepts rather than memorize formulas.

You’ll learn how to break down complex problems step by step, understand the reasoning behind formulas, apply mathematical tools to physical situations, and strengthen your analytical thinking through guided examples and practice exercises.

Mathematics is a key subject in the Baccalaureate exam and requires clear understanding and regular practice.
In this course, I help Bac students master mathematics step by step, following the official program. Lessons are explained in a simple and structured way, with many examples and exam-style exercises.
The course focuses on understanding methods, avoiding common mistakes, and gaining confidence to solve problems independently.
This class is suitable for students who want to improve their level, prepare seriously for the Bac exam, and achieve better results.

As an MSc Astronomy student, I work with mathematics every day, and over the years I’ve learned how to explain it in a way that feels clear and intuitive, not overwhelming. What I would say I’m especially good at is helping students who feel like math is “not for them”: I break problems down into simpler steps, show the logic behind the method, and help you build confidence through practice.

I have been tutoring for about 7 years and have helped students improve their grades, prepare for exams, and finally understand topics they previously found confusing.

What I can help you with:
- Homework support and catching up on missed topics
- Exam preparation (practice questions + strategy)
- Building strong foundations: fractions, percentages, algebra, equations, functions, graphs, geometry
- Improving study habits and avoiding common mistakes

How lessons usually work:
- We start with your level, goals, and what your teacher expects
- I explain concepts step-by-step, then we practice together with similar exercises
- We’ll write short summaries and you'll get optional homework so you improve between sessions
- If you have a test coming up, we can do focused exam-style practice

Lessons are available online and in person if you’re nearby. Send me a message with the student’s school level/year and what you need help with, and I’ll suggest a plan for the first sessions.
