Recent Tutoring Session Reviews
"[COVERED]: We discussed Solution Equilibria. We began by discussing concentrations of solutions and gasses. We discussed the general dissociation reaction of Ionic Salts, and the K-sp of the reaction. I emphasized the consistent generation of this K-eq, and the relationship of named K-eq's to temperature. We discussed Le Chatelier's principle, and how the K-eq's of the forward and reverse reactions are related. We discussed the act of solvation and recrystallization using two videos. We discussed the Ion Product and its parallel to the Reaction Quotient. We discussed the Lattice Energy and why it doesn't pay to memorize too many solubility rules. We defined molar solubility. We discussed the Common Ion Effect conceptually. We then discussed the 3-step method for solving molar solubility problems. [PROGRESS/CHALLENGES]: Defining saturation as Equilibrium uncovered a weakness in the student's understanding of our last session. I am glad this happened, as I was able to visually explain Le Chatelier's and how systems both approach equilibrium from starting Q, and how they adjust to stressors. Based on the student's responses, he got it, which was a critical win in this topic that is central to so much chemistry. [EXTRA PRACTICE]: The student will review what we have discussed and do two sample problems for next time. We will discuss Phase Equilibria next time."
"I covered complex math questions involving ratios, percents, rates, and quadratic equations. The student is improving quite well. I recommended that he review all the questions that we covered, and also practice with official questions released by the GMAT."
"Today we worked on some medium-difficulty math problems, including some tough word problems. Additionally, we spent time on critical reasoning and integrated reasoning portions."
"Today, we covered word problems and probability. Next session, we will cover test-taking strategies for the reading comprehension as well as covering coordinate geography. The student will also take a practice test soon so that we can gauge improvement from this point."
"We concentrated on data analysis tonight. Emphasis was placed on probability-related questions, which included formal logic and sampling with and without replacement. We also looked closely at calculating percentiles."
"We covered many types of problems from the large algebra section of the practice problems available on the review guide. She was able to solve most of these quickly and accurately. We discussed some strategies and tips for problems of the form "which quantity is greater," which tripped her up somewhat."
