Practical AP Precalculus lessons with problem solving focus

The student and Tutor reviewed concepts in chemical kinetics, including the rate of disappearance and appearance for reactants and products, and factors influencing reaction rates. They practiced applying these principles to calculate specific reaction rates and then focused on determining rate law expressions and rate constants from experimental data, including reactions with three reactants. The student was encouraged to work through additional practice questions and review solved examples as homework.

The Student and Tutor conducted a detailed review of a Biology exam paper, covering various academic concepts from cell biology, molecular genetics, cellular respiration, and human physiology to evolution and ecology. They systematically went through multiple-choice and extended-response questions, clarifying concepts and problem-solving techniques for revision.

The Student and Tutor reviewed key Chemistry concepts, including the ionization constant of water, pH calculations, and the distinctions between accuracy and precision in experimental data. They practiced titration calculations, analyzed titration curves, and extensively covered galvanic cells, focusing on half-reactions, cell notation, and standard cell potential calculations. The Student was provided with practice questions and a reduction potential chart for continued study.

The Tutor and Student engaged in an in-depth review of several advanced Biology topics, including speciation, genetic drift, selective breeding, antigenic drift and shift, and various selection pressures. They also explored biofuels, anaerobic fermentation, the structure and functions of the plasma membrane, and gene regulation. The session concluded with a review of questions related to these topics as part of the Student's exam preparation.

The Student and Tutor engaged in a detailed discussion covering various molecular biology and evolution topics. They delved into DNA modifying enzymes, the Polymerase Chain Reaction (PCR) process, and the principles and applications of gel electrophoresis. Additionally, the session reviewed evidences of evolution and the types of natural selection, with further discussion on speciation scheduled for a future lesson.

The Student and Tutor reviewed fundamental concepts in chemical kinetics, including the definition of the rate law and four key factors influencing reaction rates. They also began solving a problem on calculating reaction rates for reactants and products based on stoichiometric coefficients. The session concluded with a plan for a follow-up class to continue the academic content.
