GMAT concepts taught by Pankajbharathi
The Student and Tutor reviewed and solved multiple geometry data sufficiency problems, covering concepts such as triangle properties, areas of quadrilaterals, circle circumference, and the application of various geometric theorems. The Student practiced identifying sufficient information from given statements to answer questions. The Tutor plans to send additional geometry practice questions and a comprehensive list of theorems and formulas.
Data Sufficiency: The Three-Case Approach
Right Triangles: Pythagorean Theorem & Special Ratios
Law of Cosines
Area Formulas for Triangles and Quadrilaterals
Circle Properties: Chords and Inscribed Squares
The Student and Tutor reviewed several GMAT Data Sufficiency problems covering topics such as percentages, statistics (mean, median, range), permutations, compound and simple interest, intersections of curves, 3D distance calculations, and logarithm inequalities. They practiced identifying sufficient conditions for answering questions, discussed efficient problem-solving strategies, and clarified key mathematical formulas. The Tutor plans to provide new mock test links, while the Student will submit completed practice questions by Friday.
Data Sufficiency: Mixture Problems
Logarithmic Inequalities with Different Bases
Distance from Origin in 3D Space
Curve Intersections via Discriminant
Compound vs. Simple Interest Difference (2 Years)
Permutations: Not Adjacent Restriction
Data Sufficiency: Median vs. Mean
The Student and Tutor reviewed four data sufficiency problems from a previous assignment, covering topics such as consecutive integers, age equations, and cost comparison scenarios. They then analyzed two new problems from a practice test, focusing on modulo arithmetic for exponents and remainders, and absolute value inequalities. For follow-up, the Student was assigned to complete the second practice test and solve 50 questions from new problem sets, with the Tutor offering to provide a summary of relevant theorems.
Modulo Arithmetic & Power Cycles
Absolute Value Inequalities - Case Analysis & Distance Interpretation
Data Sufficiency - Cost Comparison with Multiple Variables
Data Sufficiency - Age Problems & Expression Evaluation Strategy
Data Sufficiency - Consecutive Integers & Prime Numbers
GMAT Geometry Scope (Data Sufficiency vs. Quant)
Student and Tutor worked on GMAT Data Sufficiency problems covering various math concepts like algebra, number properties, percentages, and ratios. They practiced evaluating statements for sufficiency and applied problem-solving techniques for inequalities and word problems. The session concluded with a discussion on upcoming homework, which includes more practice problems and mandatory weekly timed GMAT math practice tests to improve time management.
GMAT Data Sufficiency Strategy
Algebraic Manipulation & Identities in DS
Translating Word Problems to Equations
Interpreting Averages and Totals
Time Management in GMAT Quant
The Tutor and Student practiced GMAT Data Sufficiency problems focusing on various quantitative concepts. They worked through word problems involving algebra, geometry (circles), rates, percentages, ratios, and number properties (factors and remainders). The session concluded with the Tutor assigning additional practice problems for homework.
Translating Word Problems into Algebraic Equations
Rates
Work
and Time Formulas
Geometry: Circles (Circumference and Area)
Interpreting Percentage Change Correctly
Solving Systems of Linear Equations in Data Sufficiency
Data Sufficiency: Core Principles
The Tutor and Student worked on GMAT Data Insights questions, focusing on various data interpretation techniques. They practiced solving probability problems using Venn diagrams, calculated the mean and change in values from line graphs, and analyzed scatter plots to determine relationships and slopes. The Tutor assigned the remaining questions from the shared book as homework.
GMAT Integrated Reasoning & Data Insights Overview
Probability with Venn Diagrams
Line Graph Analysis & Mean Calculation
Scatter Plot Interpretation & Relationships
Slope Calculation & Comparison from Graphs
