Teaching methodology
I prefer teaching on a blank page because I feel there is a scope to take students to a world of possibilities from blank to a vast diversity of knowledge. I use a simple blank page and use different colors for the demarcation of different things. Usually, the structure of the class includes recalling the topics of the previous class, introducing a new topic, solving problems from the topic, and ending the class after completing the topic with a summary of the class. I try correlating everything to the realistic world, and it helps students to understand the topic better. The practical use of the topics is very important, and I try to provide a glimpse of the use of the topic of discussion in practical life as well. I also help my students with their assignments, homework, and test preparation. I always take regular feedback from my students and parents and also give my feedback on the students performance, so that the tutoring sessions are effective for the learner.

Lipika - About your AP tutor
I completed my Master's degree in Applied Geology. I have been teaching both online and offline for 5+ years, working with students from India and abroad. I was working as an Academic Head for an ed-tech unicorn previously. I teach all science subjects till grade 10 and physics, chemistry & geology till grade 12. I have tutored more than 500 students. I love interacting with students and exposing them to the world of different possibilities. Hence, I take up different curriculum and spread knowledge.
AP concept taught by Lipika
The student and tutor discussed DNA replication and transcription, focusing on the enzymes involved and the different models of replication. The session covered the roles of leading and lagging strands, and Okazaki fragments in DNA replication. The tutor provided flowcharts and notes to help the student review the material, and suggested that the student review conservative, semi-conservative and dispersive models.
DNA Replication Models: Conservative
Semiconservative
and Dispersive
The Role of RNA Polymerase in Transcription
Transcription Initiation and Termination
Leading and Lagging Strands with Okazaki Fragments
The Function of Enzymes in DNA Replication
ATP Hydrolysis in DNA Unwinding
The session focused on reaction kinetics, equilibrium, entropy, and Le Chatelier's principle. The student practiced interpreting concentration graphs, predicting entropy changes, and analyzing factors affecting reaction rates and equilibrium shifts. They reviewed the relationships between pressure, volume, and temperature in equilibrium systems and planned to continue practice problems in the next session.
Interpreting Concentration Graphs
Factors Causing Equilibrium Shifts
Predicting Entropy Changes (ΔS)
Relationship Between Q and K
Solid Substances in Equilibrium
Applying Gas Laws to Equilibrium
The Tutor and Student discussed DNA replication, gene inheritance, and genetic variation, including natural and engineered variations. They explored homologous recombination, genetic mapping, and chromosomal inherited disorders such as Down syndrome. The Tutor provided the student with a 12th edition AP Biology textbook to study.
Chromosomal Theory of Inheritance
Genetic Variation
Gene Linkage and Homologous Recombination
Genetic Mapping
Chromosomal Inherited Disorders
The Student and Tutor reviewed chemical equilibrium, acid-base chemistry, and titrations. They practiced calculating equilibrium constants, determining acid strength from conductivity data, and solving titration problems. The session concluded with additional practice problems related to Le Chatelier's principle, and a plan to meet again for continued review.
Equilibrium Constant (Kc) Expression
Le Chatelier's Principle
Electrical Conductivity and Acid/Base Strength
Acid Dissociation Constant (Ka)
Titration Curves and Equivalence Points
Reaction Quotient (Q) vs. Equilibrium Constant (K)
RICE Tables for Equilibrium Calculations
The student and tutor reviewed isotopes, atomic structure, and how to determine the number of protons, neutrons, and electrons in various elements and ions. They worked through worksheets involving nuclear symbols and the periodic table to practice identifying elements and calculating atomic composition. No specific homework was assigned, but the student gained a better understanding of isotopes and atomic charges.
Determining Number of Protons
Neutrons
and Electrons
Nuclear Symbol Notation
Ions and Charges
Mass Number
Atomic Number
Isotopes
The Student practiced equilibrium constant calculations, reaction quotient determination, and problems involving initial and equilibrium concentrations to find Kc. The session included a discussion on how to predict the direction of a reaction shift using Q values and implicitly used the concept of ICE tables to determine equilibrium concentrations. They plan to continue with equilibrium problems in the next session.
