I understand you're feeling lost and frustrated with your GMAT performance. Scoring a 515 with a decent Verbal score but low Quant and Data Interpretation (DI) scores is certainly a challenge.
The first thing I would suggest is not to be too hard on yourself. The GMAT is an extremely difficult exam, and it's common for students to struggle, especially in the Quant and DI sections. The fact that you've already taken it twice and are willing to keep trying shows your determination, which is admirable.
Now, let's look at some steps you can take to improve your Quant and DI scores:
1. Identify your weaknesses: Carefully analyze your performance in the Quant and DI sections. What specific topics or question types are you struggling with the most? This will help you create a targeted study plan.
2. Strengthen your fundamentals: Go back to the basics and ensure you have a solid understanding of the core Quant and DI concepts. Use official GMAT prep materials, such as the Official Guide, to work through practice problems and identify any gaps in your knowledge.
3. Practice, practice, practice: Consistent practice is key to improving your GMAT performance. Aim to do a mix of practice questions, timed sections, and full-length practice tests. This will help you build speed, accuracy, and test-taking strategies.
4. Seek expert guidance: Consider working with a GMAT tutor or joining a prep course. They can provide personalized feedback, strategies, and insights that can be invaluable in your preparation.
5. Manage your time and mental well-being: The GMAT can be mentally exhausting, so make sure to take breaks, practice stress management techniques, and maintain a healthy lifestyle. Proper time management and a positive mindset can go a long way in improving your performance.
