What are the materials and sources you followed for Geography?

I followed three sources.

1. All the NCERT Text books.
2. I had read GC Leong two-three times, though I don’t think it is necessary. It is just that I was recommended this book to start with and I finished reading this before I read the NCERT
3. Occasional articles from Down To Earth.

These should be more than enough unless Geography is your optional.
