Biology class overview
When students learn with me, they gain more than improved grades. They gain clarity, confidence, and the courage to tackle previously intimidating subjects. I transform confusion into understanding and uncertainty into academic strength — one student at a time. built on a simple belief: no subject is too difficult when it is taught the right way, by the right tutor, in a way that fits the learner. Many students struggle not because they lack ability, but because complex topics are often presented in confusing or rigid formats. At PhyChemBio Tutors Limited, we remove the veil from challenging subjects and shine light on the areas students find most difficult. Our goal is not just to help students pass exams, but to help them truly understand what they are learning. I provide personalized tutoring tailored specifically to each student’s needs, pace, and goals. I begin by identifying where the student currently stands academically, then design a structured path to guide them to where they need to be. Whether the objective is exam preparation, skill development, or mastery of a specific subject, our approach ensures measurable progress and growing confidence.

Biology concepts taught by Kelechi
The Student and Tutor engaged in a detailed physics lesson covering Newton's three laws of motion, including definitions, historical context, and common misconceptions. They applied these laws to solve various problems, focusing on calculating net force, acceleration, and distinguishing between mass and weight. The Tutor assigned practice questions related to the topics covered and discussed future sessions on physics or organic chemistry.
Newton's Third Law of Motion: Action-Reaction Pairs
Newton's Second Law of Motion: Fnet = ma
Mass vs. Weight
Newton's First Law of Motion: The Law of Inertia
Defining Force & Its Historical Context
The Student and Tutor reviewed core concepts of photosynthesis and cellular respiration. They covered the balanced equation for photosynthesis, key biochemical components like photosystems and the electron transport chain, and compared the energy flow in both processes. They also discussed the origin of plant mass and the basics of glycolysis, working through related questions. The Student was encouraged to continue studying these topics for upcoming classes.
Core Equations & Definitions: Photosynthesis and Respiration
Photosystems (PS2 & PS1) and Energy Flow
Redox Reactions: Oxidation and Reduction
Glycolysis: Glucose Breakdown
Origin of Plant Biomass
The session provided an introductory overview of fundamental physics concepts, defining physics, outlining its main branches, and discussing essential physical quantities and units. The Tutor and Student then delved into kinematics, specifically practicing calculations for distance, displacement, speed, velocity, and acceleration. They also discussed upcoming topics like forces and Newton's laws, and the Student was advised to share their course materials for future lessons.
Introduction to Physics
Major Branches of Physics
Physical Quantities & SI Units
Scalar vs. Vector Quantities
Distance vs. Displacement
Speed vs. Velocity
Acceleration
Student and Tutor reviewed fundamental concepts in biochemistry, specifically focusing on enzymes and ATP. They covered the definition, mechanism, and factors affecting enzyme activity, as well as the structure, function, and energy dynamics of ATP, including its role in endergonic and exergonic reactions. The session concluded with practice questions to solidify the understanding of these core biological chemistry principles, preparing the Student for upcoming class material.
Phosphorylation and Energetic Coupling
Enzyme Mechanism: Active Site & Induced Fit
Bioenergetics: Endergonic vs. Exergonic Reactions
Enzymes: Biological Catalysts
ATP: Cellular Energy Currency & Hydrolysis
The Tutor and Student discussed key biochemistry topics including protein primary to quaternary structures, the composition and formation of fats (triglycerides), and the properties of polar versus non-polar molecules. They also explored the structural and functional differences between various polysaccharides (glycans) and reinforced these concepts through a quick quiz. The Student plans to schedule another session for the end of next week after their upcoming test.
Lipid Structure & Formation
Molecular Polarity & Amphipathic Nature
Polysaccharide Linkages & Function
Protein Structure & Prion Diseases
Student and Tutor reviewed core biochemistry concepts, starting with the distinction between polar and non-polar substances. They then extensively compared the structures and functions of different carbohydrate forms—cellulose, glycogen, and starch—focusing on their glycosidic linkages and branching. The session also covered amphipathic lipids and their behavior in water, alongside the definition of a spontaneous chemical process. The Student reported a successful quiz result and indicated plans for test preparation in the next session.
Spontaneous Processes in Biochemistry
Amphipathic Lipids and Bilayer Formation
Comparing Carbohydrate Polymers: Glycogen
Cellulose
Starch
Polarity: Hydrophilic vs. Hydrophobic
