Note: These resources are shared for educational purposes. Errors and misinterpretations are subjective. Also note that these are the only subjects I prepared notes properly for :-) as I started my prep very late like from September 2024.

After download, view PDFs in a proper PDF reader - they might not render properly in browsers due to their file sizes.
