Akbar Leghari's book is a second source. but the way of expression is comprehensive, precise and easy to understand in very short span of time.

Jabbar junejo's book is to be read for score boosting. a very detailed book now adays available in three volumes. it is covering almost all the segments of sindhi literature.

i dont remeber the book name from where i get photo copied all the objective type questions. i am sure it is published by Faridi.

Ragrds.
