In Macroeconomics, units carrying numerical and graphs are very important. The three formulae of calculating national income is the heart of the chapter. Similarly, in the topic determination of income and employment, AD/AS approach, S/I approach, working of multiplier are the top most questions. In Indian economics, chapter 3 on economic reforms needs constant revision. The last topic of Indian economics namely a comparison between India and its neighbors is full of data like- growth rate, populations, capital formation, density of population, human development index etc. Therefore, that data has to be practiced in writing and committed to memory.
