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 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.
Protein Structure & Prion Diseases
Lipid Structure & Formation
Molecular Polarity & Amphipathic Nature
Polysaccharide Linkages & Function
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
The Student and Tutor covered fundamental biochemistry concepts, including the definitions and interconversion of monomers and polymers via condensation and hydrolysis. They discussed the four major biological macromolecules—carbohydrates, proteins, nucleic acids, and lipids—and their respective building blocks and bonds. The session also involved analyzing the polarity and solubility of various organic molecules and a detailed comparison of DNA and RNA structures and functions, concluding with the differences between prokaryotic and eukaryotic cells.
Monomers & Polymers – The Building Blocks of Life
Carbohydrates – Sugars for Energy & Structure
Proteins & Lipids – Diverse Roles & Unique Structures
Nucleotides – The Blueprint's Fundamental Units
DNA – The Stable Genetic Archive
RNA – The Reactive Information Expresser
Prokaryotic vs. Eukaryotic Cells – Fundamental Cell Organization
The tutor provided an introductory lesson on the core concepts of biology, starting with the definition and characteristics of living organisms. The session then moved to foundational cell biology, covering the cell theory, prokaryotic vs. eukaryotic cells, and a detailed comparison between plant and animal cells, including their organelles and functions.
Definition and Characteristics of Life (MRS GREN)
The Cell Theory
Prokaryotic vs. Eukaryotic Cells
Plant vs. Animal Cell Organelles
The Student and Tutor worked through a series of advanced chemistry problems covering topics such as thermochemistry, intermolecular forces, density, stoichiometry, solution chemistry, and gas laws. They collaboratively solved problems involving calculations for enthalpy of neutralization, percentage yield, partial pressures, and the number of atoms in a hydrate. At the end of the session, the Tutor and Student discussed starting biology basics before the Student's official class begins in August.
Enthalpy of Neutralization (ΔH)
Calculating Atoms in Hydrate Compounds
Partial Pressure (Dalton's Law)
Mass from Molarity and Volume
Percentage Yield in Reactions
Density and Volume Displacement
Identifying Intermolecular Forces (IMFs)
The Student and Tutor reviewed various advanced chemistry concepts and problem-solving techniques, including theoretical yield, molecular formula determination from percentage composition and gas density, writing ionic equations, calculating molar concentrations, and titration. They also covered enthalpy changes from reactions and bond enthalpies, and extensively discussed the definitions and identification of oxidation-reduction reactions and agents. The next session was scheduled to continue their review.
Empirical & Molecular Formulas from Composition
Ionic & Net Ionic Equations
Molar Concentration of Ions in Mixed Solutions
Titration Calculations
Enthalpy Change (ΔH) & Heat Released
Redox Reactions: Oxidation & Reduction Agents
Limiting Reagent & Theoretical Yield
