My focus is DSE and ISI as my English is very very weak. Will you please suggest which book (and topics) to follow for DSE/ISI masters econ (Apart from Chiang, Sydsaeter-Hammond and Simon-Blume)? Is the combo of Sydsaeter-Hammond and Simon-Blume enough for DSE/ISI or any further reference needed?

(I have bachelors in commerce and have working knowledge of maths upto 10+2 NCERT level.)

Your suggestion will build up my career.
