 It is a continuously evolving repository and I will keep adding more resources to it. If you have any suggestions or want to contribute to this repository, feel free to open an issue or a pull request.
 
 ## Table of Contents
+
+I will divide the resources into different levels of learning and will also provide the best resources to learn each topic. The levels of learning are:
+
+- **Fundamentals before Data Science Stage 1**
+- **Core Data Science Fundamentals**
+- **Intermediate Data Science**
+- **Advanced Data Science**
+- **Data Science Projects**
+- **Guide to Data Science Interviews**
+- **Recommended Timeline to follow this roadmap**
+- **Tips/Tricks for following the roadmap**
