your memory is almost unlimited
The question should be, “How can I increase my memory capability?”
To do this, eat healthy foods, strenious exercise(seriously), relate things to one another to remember things and by this I mean that if you are studying something, and the first letter of each word spells out something like PLATE, you could remember it better by thinking of this. Little simple tricks like this work
I have also learned that stress does not help memory. If you need to, take 5 minutes out of each day just to write down what ever is on your mind, whether you are pissed or not.
Also, the best way to learn things is to review it about every day, maybe 20 minutes out of each day to review what you have learned.

Take up abacus classes, it will increase the speed of ur thinking It works for me. I can do math sooo dam easy, gimme any at least 10 numbers to add and ill hit u up an answer in the blink of an eye

Stop eating paint chips.

the most important step is what you have done…..identifying an objective. The wonderful human mind will do the rest. You will find you remember more and more simply because you consciously made it an objective. I was in sales for years and wanted to remember names……..I became phenomenal at it…just because it was important to me.

First rule…
Never copy and paste anything using the computer… It just make your memory lazy.
second rule…
You don’t need to increase your memory capacity, you only need to practice everyday. What you are looking for is LONG term memory, whatever you do will increase short term…
I will read more answers to know a little more…
BTW, I am from Mexico, and the only way to do not forgot English, is by looking any task to make you to practicing your skills (Like Yahoo answer from here, i know it is not perfect but, It will some day).

You will have so much work to do I think anything beyond the course material will be a distraction.
You are looking at your study the wrong way. Finance isnt about rote learning (and at this level nothing should be) it is about understanding the concepts, what a beta represents and how changing the other variables in the financial models effects it and why.
Paradoxically financial studies are very simple, very elegant, just very abstract. There is not a whole lot to remember really but a lot to understand.
Trying to expand ones memory is pointless, your brain is like your muscles, use it or loose it, simply studying is the best way to enhance ur brain power (and good sleep and excellent diet).
Oh and by the way, you arent going to master everyting in finance when you start, that will take a very very long time.
