Best book for the starters of any competitive exam. For exams other than CGL and PO it is the ultimate book. Grammar along with the vocabulary section is excellent and one can get atleast 60% common in vocabulary part reading this book alone.
Objective General English by S.P Bakshi is a good book for competitive exams but paper quality is not up to the mark. It has very cheap, transparent & thin pages which do not feel like original. I guess Arihant should provide 3D logo to stop counterfeiting
