pls don't buy this book if u really want to learn hindi in 30 days.. its a total waste. u would take atleast 4 or 5 months to learn if u follow these instructions. its just a hindi grammar split into 30 chapters saying that we can learn in 30 days. u can't learn even if u learn 24 hours a day and our brain can't concentrate more than an hour continuously. pls don't waste ur money..
