Great to hear that you’re committed to improving your Data Interpretation (DI) skills for the GMAT. Scoring 70 in your last mock indicates there’s room for growth, and with the right strategy, you can significantly boost your performance. Here’s a comprehensive plan to get you started effectively:
1. Understand the DI Section Thoroughly
Before diving into practice, ensure you have a solid understanding of what the DI section entails:
• Components: Typically involves interpreting data from tables, charts, graphs, and other visual formats.
• Question Types: Includes selecting best statements, determining the truth of statements, calculating specific values, and more.
• Skills Tested: Data analysis, critical reasoning, mathematical proficiency, and efficient information processing.
2. Assess Your Current Performance
Since you’ve scored 70 in your last mock, it’s crucial to identify where you’re losing points:
• Review Mistakes: Go through each incorrect DI question to understand whether the error was due to misunderstanding the data, calculation mistakes, time management, or misinterpreting the question.
• Identify Patterns: Determine if specific types of DI questions (e.g., bar graphs, pie charts, line graphs) are consistently challenging for you.
3. Develop a Structured Study Plan
A well-organized approach will help you make steady progress. Here’s how to structure your prep:
