Science becomes much easier when each idea is explained clearly and connected to familiar examples. In my online lessons, I help middle- and high-school students understand challenging topics in chemistry, biology, physics and general science without relying only on memorization.
These lessons are suitable for students who:
Find science difficult or confusing
Need help with homework and school assignments
Want to improve their examination results
Have missed important foundational concepts
Need additional practice with calculations, diagrams or scientific terminology
Want to become more confident before a test
Every lesson is adapted to the student’s grade level, school curriculum and current difficulties.
Subjects covered
Chemistry
Atomic structure and the periodic table
Chemical bonding
Elements, compounds and mixtures
Chemical reactions and equations
Acids, bases and salts
Mole concept and basic stoichiometry
Solutions and concentration
States of matter
Organic chemistry fundamentals
Biology
Cells and cellular organelles
Human body systems
Respiration and circulation
Genetics and inheritance
Nutrition and digestion

How the lessons work
Before the lesson, students can share their textbook chapter, syllabus, worksheet or difficult topic. This allows me to prepare a lesson that directly matches what they are studying in school.
A typical lesson includes:
A short review of previous knowledge
A clear explanation of the main concept
Diagrams, examples and everyday applications
Guided practice questions
Independent questions to check understanding
Correction of mistakes
A brief summary and revision task
I do not simply provide answers. I help students understand why an answer is correct and how to solve similar questions independently.
Homework and examination support
I can help students with:
Understanding homework questions
Revising difficult chapters
Practising multiple-choice questions
Solving science calculations
Preparing short and long answers
Reading and interpreting diagrams
Understanding scientific experiments
Preparing for school tests and final examinations
Creating a manageable revision plan
Identifying and improving weak topics
I provide guidance and feedback while encouraging students to complete their own assessed work.

About Me
Hello, I’m Sarfraz, a patient and supportive science tutor with around five years of teaching and tutoring experience. My main academic background is in Chemistry, and I also have professional training in education.
I enjoy working with middle- and high-school students who need clear explanations, help with homework, exam preparation, or support in rebuilding weak foundations. Many students believe science is difficult because they have missed one or two basic concepts. I help them identify those gaps and understand each topic step by step.
My lessons are calm, organized, and interactive. I use simple language, everyday examples, diagrams, guided questions, and regular practice. I encourage students to ask questions freely and never make them feel uncomfortable about mistakes. Instead of giving answers directly, I help students understand the reasoning so they can solve similar questions independently.
I mainly teach general science, chemistry, biology, and basic physics to middle- and high-school learners. I can also support students with scientific calculations, graphs, experiments, assignments, revision, and test preparation.
I enjoy teaching students who are willing to learn, even when they currently lack confidence. My goal is to make lessons understandable, useful, and suited to each student’s pace.
