A mini-book to the GK-2019 (The detailed one). It contains all the relevant topics and a brief introduction to every one of them but for better knowledge, one should be having the detailed edition. Good for keeping as a last minute revision notes.
For Rs.25/- it's a very good book that you could have with you. It is especially useful for students & current affairs enthusiasts. It's a tiny guide packed with all info on India from its history to current politics, sports, awards, economics, people and their names.
This is one of the best books for General Knowledge that one can have. The book has to the point notes that help for last time revision for the competitive exams like CDS, PO etc.. The book has all at one place, but prefer it as a secondary book for revision not primary for reading the first time..
