Solving 100 of the Hardest GMAT Problems [3/6]
In this video, I solve 100 of the hardest GMAT problems, subdivided into six parts: Geometry, Algebra, and Arithmetic, each further divided into two types of problems you'll see on the GMAT: Problem-Solving (PS) and Data Sufficiency (DS) problems.
In the Geometry section, you'll be expected to solve problems involving angles and lines, angles and polygons, triangles, trapezoids, and parallelograms, circles, coordinate geometry, and parabolas.
In the Algebra section, you'll be expected to solve problems involving algebraic expressions and linear equations, factoring and quadratic equations, inequalities, rates, ratios, percents, interest, profit, work, mixture problems, mean, median, mode, range, standard deviation, and probability.
In the Arithmetic section, you'll be expected to solve problems involving absolute value and inequalities, quotients and remainders, even and odd numbers, scientific notation, rules of exponents and square roots, sets, counting methods, statistics, and probability.
