Hello Kritika,

To prepare well for your entrance examination for masters in economics from IIT/IGIDR/ISI and DSE, you must go through all the previous years question papers and brush up all your concepts thoroughly.

You should study the whole syllabus and study on regular basis as this is one of the most toughest exams to crack.

Keep practicing mock test papers and work hard to achieve your goals.

Hope it helps.

Good Luck!
