+## Suggested Learning Path
+
+1. **Start Here (Beginner):**
+   - [CodeWithHarry / The-Ultimate-C-Programming-Course](https://github.com/CodeWithHarry/The-Ultimate-C-Programming-Course)  
+   - [h0mbre / Learning-C](https://github.com/h0mbre/Learning-C)
+
+2. **Next Steps (Beginner → Intermediate):**
+   - [sbccas / c-programming-tutorials](https://github.com/sbccas/c-programming-tutorials)  
+   - Practice writing small programs and algorithms.
+
+3. **Level Up (Intermediate → Advanced):**
+   - [nCally / Project-Based-Tutorials-in-C](https://github.com/nCally/Project-Based-Tutorials-in-C)  
+   - [ShravanDalavi / CProgrammingProjects](https://github.com/ShravanDalavi/CProgrammingProjects)
+
+4. **Always Useful:**
+   - [mcinglis / c-style](https://github.com/mcinglis/c-style) – Follow this style guide throughout your learning.
+
