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 reviewed the concepts of molecular polarity, differentiating between polar and non-polar molecules based on charge distribution and molecular geometry. They also discussed determining an element's bonding potential based on its valence electron configuration and explored the conventions of drawing polarity arrows in Lewis structures. The next session will cover gas laws.
Polar vs. Non-polar Molecules
Electronegativity and Bond Polarity
Molecular Geometry and Polarity
Valence Electrons and Bonding Capacity
The Tutor and Student reviewed concepts related to heat, specific heat capacity, and phase changes. They practiced applying these concepts through examples and problem-solving, focusing on understanding heating curves and the energy involved in phase transitions. The Tutor assigned practice questions for future review.
Specific Heat Capacity vs. Molar Heat Capacity
The Heat Transfer Equation (Q=mcΔT)
Phase Changes and Energy
Intermolecular Forces (IMFs) and Heat Capacity
The tutor and student reviewed fundamental concepts of thermal physics, including temperature, thermal energy, heat, and the ideal gas law. They practiced unit conversions, applied the ideal gas law to solve for moles, and discussed the Maxwell-Boltzmann distribution and its relation to particle speed and temperature.
Temperature vs. Thermal Energy vs. Heat
Ideal Gas Law and its Components
Maxwell-Boltzmann Distribution
Absolute Zero and Temperature Scales
The student and tutor worked through practice problems focusing on stoichiometry, molar mass calculations, Avogadro's constant, and thermochemical principles including endothermic and exothermic reactions. They discussed problem-solving strategies for heat and work calculations and applied these to relate reaction enthalpies to mass and moles of substances. Future sessions were planned to cover Lewis structures.
Moles and Chemical Formulas
Stoichiometry and Mole Ratios
Thermochemistry: Endothermic vs. Exothermic Processes
Avogadro's Constant and Molar Mass
Stoichiometric Calculations Using Enthalpy Changes
Calorimetry: Heat Capacity and Temperature Change
The tutor and student reviewed various chemistry concepts including molecular orbital theory, covalent bonding, Lewis structures, formal charges, intermolecular forces (LDFs, dipole-dipole, hydrogen bonding), hybridization, molecular geometry, and resonance structures. They worked through several practice problems and discussed concepts related to bond polarity, bond order, and molecular properties.
VSEPR Theory and Molecular Geometry
Lewis Structures and Formal Charge
Molecular Orbital Theory and Bond Order
Intermolecular Forces (IMFs)
The tutor and student reviewed intermolecular forces (London dispersion forces, dipole-dipole, and hydrogen bonding) and their relationship to boiling points. They practiced predicting boiling points based on molecular structure and intermolecular forces, and discussed the concept of distillation as a separation technique. The tutor also explained 3D molecular representation using wedge and dash notation.
