Recent Tutoring Session Reviews
"Today we covered: Ksp calculations, Le Chatelier's principle review, common ion effect, solubility quotients and factors that may affect solubility. The student also completed a quiz at the beginning of his session which he did really well on. Towards the end of the session, the student worked through a free response from the AP chemistry exam. He was able to work through the problem with little difficulty. We also answered questions out of a packet given to him by his teacher which contained questions from old AP chemistry exams. I have no concerns at this time."
"The student recently had a quiz in her AP Chemistry class on acid-base equilibrium that she had missed 5 questions on. During our session we reviewed these questions and also reviewed her current homework assignment. She is struggling with understanding concepts in acid-base equilibria and how to solve acid-base titration problems, so we focused there. At the end of our session she had a better understanding of the concepts and was able to solve her homework problems. She is going to read through the chapter in her book before our next session."
"We went over some long-form practice problems for the AP Chemistry exam. The problems we went over involved various subjects, including equilibrium, acid-base reactions, significant figures, and general gas laws. We also went over the topic of electrochemistry and redox reactions. Overall, we were able to get some great practice in, and the student understood the material very well."
"Today was largely dedicated to concluding the organic chemistry lecture, and all of the concepts I felt the student would need to know for the AP test. This included all of the main functional groups as well as a couple of the important reactions that may be addressed on the test. We concluded the session by starting to review some of the question found on the practice AP tests. I will be using these tests with the student in order to make sure that all areas of chemistry have been covered and that he is comfortable addressing all aspects of the test. Next session will be centered around more test questions as well as chemical kinetics."
"The student had worked through a series of Chemistry practice problems with accompanying detailed explanations while he was away in India. He had questions about the four gas laws (Boyle's, Charles', Avogadro's and Dalton's). We went over examples and worked a series of problems with increasing difficulty out of my college chemistry textbook and after about an hour, he seemed to have mastered the fundamentals. We then moved onto stoichiometric applications to the gas laws (applying the gas laws to chemical reactions that generate gases)."
"For my first session with the student we covered thermodynamics. He understood all of the topics very well by the end of the session, including energy diagrams. By the end of the session, we exhausted all of the problems at the end of his book, and worked on some of the problems from my chemistry book."
"The student and I covered Solutions and Electrochemistry for her upcoming test. We specifically went over how to balance redox reactions in acids and bases. We will have another session before her test so we can review the material again."
"Today the student wanted me to go over molecular geometries and orbital hybridization. We went over the various bond angles and how they are associated with the number of electron orbitals surrounding the central atom of interest, as well as the names associated with each of these. The geometries were discussed as groups related to the total number of electron orbitals surrounding the central atom (i.e. for six groups: octahedron, square planar, etc.). The concept of orbital hybridization was discussed, including why it exists and how to derive the various orbital hybridization states."
"The student has a quiz on Tuesday over the ideal gas law. We reviewed his notes and he did several practice problems while I checked his work. Topics involved: partial pressure, converting pressure to different units, using ideal gas laws to solve for an unknown, knowing that original conditions are equal to final conditions so can solve for unknown."
"The student and I covered topics specifically focusing on ideal gas law, what properties of gasses make them behave non-ideally, using information about standard temperature and pressure, and solving problems involving reactions of gases. The student seemed to grasp the material fairly well and seems prepared for his upcoming test."
"The session covered Stoichiometry. So far there were worksheets without grades. The student is very bright and only needed guidance to become accustomed to the steps involved in stoichiometry problems. There were no concerns, and there were plenty of problems for extra practice on her own, which I looked over to make sure there was not anything that had not been covered."
"Today, the student and I met for the first time. We worked on his AP chemistry assignment, as he needed to finish 24 multi-part questions by midnight. He tried to skip too many steps, but once we organized a plan of attack for every sort of question he encountered, he began getting questions correct. He is bright and just needed a nudge in the right direction."
