How to increase my memory power?

If you have read my posts then you will know that I am in between of my exams. And I am dead worried about clearing them all. These exams have taken up my peaceful sleep.

So, how do I increase my memory power, I have seen quite a few things on the internet. People are recommending that I eat Almonds, Vegetables and a few are recommending that I increase my vitamin intake.

But I am confused, I do have good concentration levels and I do remember a lot of things that I have studied but wouldn't it be great if I could remember each and every detail and if I could be a topper in my class or even in the City?

Well that's what I am trying to achieve and if you have any tips then do not forget to share them below.
