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 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.
Mass from Molarity and Volume
Calculating Atoms in Hydrate Compounds
Partial Pressure (Dalton's Law)
Percentage Yield in Reactions
Density and Volume Displacement
Identifying Intermolecular Forces (IMFs)
Enthalpy of Neutralization (ΔH)
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.
Titration Calculations
Redox Reactions: Oxidation & Reduction Agents
Enthalpy Change (ΔH) & Heat Released
Molar Concentration of Ions in Mixed Solutions
Ionic & Net Ionic Equations
Empirical & Molecular Formulas from Composition
Limiting Reagent & Theoretical Yield
The Student and Tutor reviewed various chemistry concepts, including molecular geometry, VSEPR theory, polarity, and periodic trends such as ionic radius, lattice energy, melting points, ionization energy, and electron affinity. They worked through specific examples provided by the Student and clarified conceptual misunderstandings related to electron domains, bond angles, and the reasons behind periodic trends. The Tutor confirmed availability to assist the Student with biology in the upcoming semester, addressing the Student's future academic plans.
VSEPR Theory: Molecular Geometry & Polarity
Isoelectronic Series & Ionic Radius Trends
Melting Points: Lattice Energy & Ionic Radius
Ionization Energy (IE)
Electron Affinity (EA)
The Student and Tutor worked through several advanced chemistry problems, including calorimetry calculations, bond enthalpy determinations, photon energy and wavelength calculations, and applications of Hess's Law. They focused on correcting the Student's approach to these problems and clarifying formulas and concepts. The Student has an upcoming test on these topics and plans to engage in more practice.
Calorimetry: Calculating Heat Transfer (Q) and Enthalpy Change (ΔH)
Bond Enthalpies: Estimating Enthalpy Change (ΔH)
Photon Energy and Wavelength Calculations
Hess's Law: Combining Reactions for ΔH
The Tutor and Student reviewed various chemistry concepts including dilution, titration calculations, percentage composition, and hydrate formulas. They practiced solving problems related to these topics, with a focus on balancing chemical equations and applying relevant formulas like M1V1=M2V2 and N=MV. The next session is scheduled for Monday afternoon to continue practice.
Dilution Calculations (M₁V₁ = M₂V₂)
Neutralization Reactions and Titration
Percent Composition by Mass
Calculating Atoms in Hydrated Compounds
The Student and Tutor reviewed key organic chemistry concepts, focusing on identifying functional groups like hydroxyl, carboxyl, amino, and carbonyl, and their associated organic compounds. They practiced recognizing these groups and discussed their presence in biological macromolecules. The session also covered essential biochemistry topics, including enzymes, oxidation-reduction, and an overview of glycolysis and the Krebs cycle in preparation for an upcoming exam.
Glycolysis and the Krebs Cycle: Cellular Energy Production
Oxidation-Reduction (Redox) Reactions
Organic Functional Groups: Identification & Macromolecules
Enzymes: Biological Catalysts
