GMAT Problem Solving is a section in the GMAT exam that assesses a candidate's ability to solve quantitative problems using basic mathematical concepts. This section consists of multiple-choice questions that cover a wide range of topics, including arithmetic, algebra, geometry, and data analysis. Here are the types of questions you can expect in the GMAT Problem Solving section:

1. Arithmetic:
- Questions involving basic arithmetic operations such as addition, subtraction, multiplication, and division.
- Questions on percentages, ratios, averages, and proportions.
- Questions on number properties, factors, and multiples.

2. Algebra:
- Questions on solving linear and quadratic equations.
- Questions on inequalities and absolute values.
- Questions on functions, exponents, and logarithms.

3. Geometry:
- Questions on lines, angles, triangles, and polygons.
- Questions on circles, cylinders, spheres, and cones.
- Questions on area, perimeter, volume, and surface area.

4. Data Analysis:
- Questions on interpreting and analyzing data presented in tables, charts, and graphs.
- Questions on probability and statistics.
- Questions on data sufficiency.


GMAT Data Sufficiency is a unique section that assesses a candidate's ability to analyze and interpret data to determine whether the given information is sufficient to answer a particular question. In this section, you are not required to solve the problem but rather evaluate the sufficiency of the information provided. Here are the key elements of the GMAT Data Sufficiency questions:

1. Format:
- Each question consists of a stem followed by two statements, labeled as (1) and (2).
- You need to determine whether the statements, individually or combined, are sufficient to answer the question.

2. Answer Choices:
- Instead of traditional multiple-choice options, you'll have the following answer choices to select from:
- Statement (1) alone is sufficient but statement (2) alone is not sufficient.
- Statement (2) alone is sufficient but statement (1) alone is not sufficient.
- Both statements together are sufficient, but neither statement alone is sufficient.
- Each statement alone is sufficient.
- Statements (1) and (2) together are not sufficient.

3. Analytical Skills:
- Data Sufficiency questions require logical reasoning and critical thinking skills.
- You need to determine what additional information is required to solve the problem and evaluate the sufficiency of the given statements.
- It's important to avoid solving the problem but focus on identifying the minimum amount of information needed to answer the question.

In both the Problem Solving and Data Sufficiency sections, it is crucial to manage time effectively, read the questions carefully, and choose the most appropriate approach to solve the problem or evaluate the sufficiency of the given information. Practice and familiarity with the different question types will help improve your performance in these sections.
