GS1 usually takes most times of aspirant as subjects like History and Culture are highly time consuming but not really rewarding. I would suggest you to not devote much time to these topics as either the questions would be so easy that everyone would be able to write something meaningful or so difficult that most of the candidate will have no idea what they are suppose to write.
Booklist
- History – TN Board 11th NCERT, Modern Spectrum, Few chapters from TMH
- Culture – Nitin Singhania’s handwritten notes+GK Today notes
- Geography – NCERT, G C Leong, Vajiram class notes
- Society – Vision IAS Notes, Current affairs
I made revision notes for all material. For Spectrum, I got the summary pages at the end of each chapter photocopied and wrote extra stuff on them for last minute revision.
