The notes for the chapter "Management of Natural Resources" taken from 2 different sites.
Just the other day, I found some notes, solved and unsolved papers, etc in one of the sights, so I thought I'd poast them here. There are a lot of files!!!
These are some notes for the chapter "Heridity and Evolution". Sample questions are also added.
Here are some notes for the chapter "Periodic Classification of Elements", Chemistry Class X. All the notes were typed, so excuse me if there are spelling mistakes.:)
