Do I need coaching to prepare for AIBE Exam?

To identify the best reference material, candidates should check: 

AIBE Reference material is free of grammatical errors 
Legal concepts are explained clearly 
All illustrations, examples, and other such representations are accurate 
The reference book for AIBE is reviewed by law experts
It has contained case-laws for a better understanding
It is based on AIBE 20 syllabus only

For the AIBE exam, the best books are bare acts (without comments) for core subjects like the new BNS, BNSS, BSA, CPC, and others, alongside comprehensive guides like Universal's or Taxmann's publications, and subject-specific texts like Durga Das Basu for the Constitution or C.K. Takwani for CPC, focusing on recent editions with the latest legal changes. 

If you have topped while pursuing law there is still some chance. But if you were an average student who have not prepared even once for the exam, it is next to impossible to prepare for the exam in one month. 

The AIBE 21 Exam will be held in pen-and-paper mode. No notification mentioning that it will be held in online mode has been released by the council yet.
