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 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.
Bond Enthalpies: Estimating Enthalpy Change (ΔH)
Hess's Law: Combining Reactions for ΔH
Photon Energy and Wavelength Calculations
Calorimetry: Calculating Heat Transfer (Q) and Enthalpy Change (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.
Percent Composition by Mass
Calculating Atoms in Hydrated Compounds
Neutralization Reactions and Titration
Dilution Calculations (M₁V₁ = M₂V₂)
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
The Student and Tutor reviewed key concepts in microbiology and biochemistry, beginning with microscope types, properties, and various staining techniques, including Gram staining. The session then shifted to core metabolic processes, discussing enzyme function, oxidation-reduction reactions, glycolysis, the Krebs cycle, photosynthesis, and aerobic versus anaerobic respiration. The Tutor advised the Student to review their notes and suggested a potential follow-up class to cover remaining study guide topics before an upcoming exam.
Specialized Staining Methods
Aerobic vs. Anaerobic Respiration
Core Metabolic Pathways
Oxidation-Reduction (Redox) Reactions
Introduction to Metabolism & Enzymes
Staining Techniques & Dyes
Microscope Fundamentals
The Student and Tutor continued their chemistry and biology review, focusing on chemical bonding, the pH scale, definitions of acids and bases, organic and inorganic compounds, and key functional groups. They also covered the major macromolecules: carbohydrates, lipids, proteins, and nucleic acids. The session concluded with the Student practicing multiple-choice questions covering topics from this and previous lessons, with a plan to address remaining curriculum points in their next meeting.
Acids
Bases
and the pH Scale
Macromolecules II: Proteins and Nucleic Acids
Macromolecules I: Carbohydrates and Lipids
Polarity and Organic vs. Inorganic Compounds
Chemical Bonds: Ionic
Covalent
The Student and Tutor reviewed several microbiology topics, including inclusions, the prokaryotic plasma membrane, endosymbiotic theory, endospores, and glycocalyx. The session then transitioned to fundamental chemistry, covering the definition of chemistry and matter, the structure of atoms, elements, electronic configurations, and the formation of ions (metals vs. non-metals). The Student practiced determining electronic configurations and identifying ion types, and they planned to continue with chemical bonds and other chemistry topics in the next session.
Inclusion Bodies
Prokaryotic Plasma Membrane
Endosymbiotic Theory of Eukaryotic Evolution
Endospores
Sporulation
and Germination
Fundamental Atomic Structure and Elements
