The session covered elimination reactions (E1, E2), distinguishing them from substitution reactions (SN1, SN2), and the Zaitsev and Hoffman rules for predicting major products in elimination reactions based on base size. The student practiced identifying strong bases and bulky reactants to predict reaction outcomes. The next step involves reviewing these concepts to reinforce understanding.

The session covered cellular respiration, including glycolysis, the Krebs cycle, and the electron transport chain, with a focus on aerobic and anaerobic respiration. The Student reviewed each step, discussing the inputs, outputs, and locations within the cell. The plan is to continue with the Krebs cycle and other related concepts in the next session.

Sharon and Sana reviewed linear programming, focusing on maximizing profit and minimizing costs with constraints, including word problems. Sana practiced setting up equations and identifying constraints. Sharon recommended drawing graphs to visualize feasible regions and intersection points.

Sharon taught Stephen about Grignard reactions, focusing on the nucleophilic nature of the Grignard reagent and its reactions with aldehydes, ketones, and esters. Stephen practiced identifying positive and negative charges in molecules to predict reaction mechanisms. Sharon assigned Stephen to memorize the first 20 elements of the periodic table to better understand the charges of different elements.

Sharon and Sana recently focused on key linear algebra concepts, specifically covering the matrix representation of linear equations and the technique of Gaussian elimination. Sana gained practical experience by converting various equations into their matrix forms and then solving these systems through the application of row operations to eliminate variables. Their work involved several examples, including one that presented the added complexity of fractional coefficients. Sharon concluded the lesson by recommending further practice to reinforce Sana's understanding of these methods.

Sharon and Stephen reviewed SN1 and SN2 reactions in organic chemistry, focusing on steric hindrance and charge distribution. They then practiced evaluating limits, including piecewise functions and algebraic manipulation. Stephen was assigned to review the material and put any questions in their WhatsApp group.
