Masters

Hi Himank!
You can refer to the following books for preparation:
1. Micro-economics: Hal Varian (Intermediate Micro-economics), Hal Varian Workbook, Osborne (for Game Theory), Bernheim & Whinston (also a good book)
2. Macroeconomics: Dornbusch and Fischer, O. Blanchard, Development Economics by Debraj Ray (for Solow and Harrod Domar growth models), William Branson's book (for general equilibrium questions). Alternatively, you can get hold of the Macro reading prescribed by Delhi University for the 2nd year students (3yr program). This should have most of the relevant content from the first three books.
3. Econometrics and Statistics: Gujaratis Introductory Econometrics, Degroot and Schervish
4. Mathematics: Sydsaeter and Hammond, A. Chiang's "Fundamental Methods of Mathematical Economics". However, the exam also goes into a fair amount of maths that you learnt in Classes 11 and 12 in school. I recommend digging up those old R.S. Aggarwal/ S.P. Sharma books and go through the relevant topics in those books (i.e. solve questions; the relevant topics are probability, functions, limits and continuity)
