I saw on a teleshopping show that u can improve u're memory(I'm not talking about computer memory) to almost photographic memory. All that needs to be done is buy a couple of audio or video cassettes, books, etc.. the whole thing cost about a 1000 rs & just by following the techniques & doing some simple exercises u can have photographic memory. Is this possible? I mean just imagine anyone planning to give their engineering or medical exams or just about any exams can do so by preparing a week or 2 in advance & also hope to get good results.
