This was very drawly, not very to the point, and not for any good, it explains the methods, but is incredibly bloated, wouldn't recommend reading this book for mnemonics. A better book would be something like Moonwalking With Einstien by Foer Joshua. I gave it 2 stars because it did give me some of the knowledge I wanted, not very well, and would simply be better off reading just Foer's book if you had to choose. It was also formatted badly, and was very Indian, and made many references that predicated on you know these things, like Indian politicians, states, etcetera, which made it harder to parse.
