Zeina - About your AP tutor
Hello! I’m Zeina Koolivand, an enthusiastic AP Chemistry tutor with a Master’s in Analytical Chemistry. My passion for teaching stems from a desire to demystify complex concepts and connect them to real-world applications. I believe that chemistry is not just a subject but a lens through which we can better understand the world around us. My teaching philosophy centers on creating a supportive and nurturing learning environment where students feel empowered to ask questions and explore their curiosities. Every student is unique, so I tailor my approach to meet individual learning needs and styles. By utilizing a mix of hands-on experiments, visual aids, and relatable examples, I strive to make the learning experience both engaging and memorable. I am committed to building my students’ confidence and fostering critical thinking skills. My goal is to help you grasp the material and develop a deeper appreciation for chemistry as a subject. Whether you’re in high school, college, or navigating your professional career, I’m here to guide you on your journey to success in AP Chemistry. Let’s embark on this exciting learning adventure together, and unlock your potential in the fascinating world of chemistry!

Teaching methodology
As an AP Chemistry tutor, I tailor my teaching approach to cater to students of all backgrounds, whether they are in high school, college, or adult learners returning to education. My teaching methodology is designed to be inclusive and adaptable, ensuring that every student can engage with the material at their level. Problem-Solving Focus: I emphasize problem-solving as a critical skill in chemistry. Through targeted practice, I guide students in tackling complex questions and breaking them down into manageable steps. This not only builds their confidence but also equips them with the tools to approach future challenges independently. Engagement and Interactivity: To foster a dynamic learning environment, I incorporate interactive discussions that encourage students to express their thoughts and ask questions. This dialogue helps students connect with the material on a deeper level and promotes a collaborative atmosphere where ideas can be shared and explored. Hands-On Practical Sessions: Understanding chemistry often requires a tactile approach, so I integrate hands-on experiments into my sessions whenever possible. These practical experiences not only reinforce theoretical concepts but also spark curiosity and excitement about the subject. Concept-Focused Explanations: I believe that a strong foundation in fundamental concepts is essential for success in chemistry. My detailed explanations focus on core ideas, ensuring that students understand not just how to solve problems but also the reasoning behind the methods. This depth of understanding is crucial for mastering complex topics.

AP concept taught by Zeina
Zeinab and Ahmed reviewed solution concentrations, enthalpy of solubility, and solubility product (Ksp) calculations. Ahmed practiced calculating molarity, mass percent, mole fraction, and Ksp. For the next session, Ahmed was asked to review precipitation reactions, and Zeinab plans to cover the reaction quotient, Le Chatelier's principle, and predicting precipitate formation.

Zeinab and Ahmed discussed chemical equilibrium, covering reversible reactions, equilibrium conditions, and the equilibrium constant K. They worked through examples of calculating K and manipulating equilibrium expressions. Ahmed was assigned practice questions from the textbook and will continue with equilibrium quotient and Le Chatelier's principle in the next session.

Zeinab tutored Rishita on writing chemical formulas for ionic compounds, working through a worksheet to practice identifying ions, swapping charges, and writing correct formulas, including those with polyatomic ions and transition metals. Rishita completed exercises, receiving feedback and corrections from Zeinab. Zeinab requested Rishita's syllabus or textbook PDF to better align future lessons with her school's curriculum and suggested adjusting the lesson time to better suit Rishita's schedule.

Zeinab and Ahmed discussed different types of bonding—metallic, ionic, and covalent—and their effects on material properties like conductivity and hardness. They also covered network covalent structures like diamond, graphite, and silica, as well as molecular solids and heating curves. Zeinab will send Ahmed study materials, and they plan to review reaction rates in the next session.
Ionic Bonding
Alloys vs. Pure Metals
Metallic Bonding
Covalent Network Structures
Graphite Structure and Properties
Heating Curves and Phase Changes
Zeinab tutored Ahmed on chemical kinetics, covering reaction rates, concentration vs. time graphs, rate laws, and experimental determination of rate orders. Zeinab explained why experimental rate laws may not match stoichiometric coefficients due to multi-step reactions and the rate-determining step. Ahmed was assigned practice problems from the end of the chapter, and the next session will cover first-order characteristics, collision theory, and solution equilibrium.
