What is your single point source for Geography?

We all have Spectrum for Modern Indian History, TN for ancient and medieval, and Laxmikanth for polity. These sources cover most of the MIH, Ancient & Medieval, and Polity questions in prelims. However, I want to knowhow do you tackle geography (Physical + Human). 

I studied in vision so I have 4 NCERTs, 4 books from Vision and 2 copies of handwritten notes from their lectures = Total 10 books. All the material is scattered. Can you please recommend a good single point source for geography which covers atleast 75-80% of the syllabus?
