Before choosing the books for preparation, you have to decide whether you are going to buy book only for postal exam or to prepare for other exams also.
My advice is to buy standard books to prepare for all examinations. These books cover well all topics. If you are already preparing for SSC, IBPS, State PSC exams, then this exam will be easier to you.
Recently Postal Assistant / Sorting Assistant Exam Pattern & Syllabus restructured similar to the Bank clerical examinations.

If you already have the standard books bought for other examinations, just use it.
