Hello Student,

As per your question I would say to follow some basic books like microeconomics by HL Ahuja, macroeconomics books by ML jhingan and Macro economic theory by RGD Allen. Ncert book on micro and macro economics should be followed for basic understanding of economics. Problems of philosophy by DD Raphael, John Hoppers: Introduction to philosophical analysis for subsidiary course in philosophy, For Geography go for Savindra Singh textbook on Geomorphology, Population Geography by RC Chandana.

I hope this information is clear.

Thank You
