You could write them out in permanent marker on your forehead so that every morning when you wake up, you will see it. Then I bet you will always remember them.

I got a tattoo of them on my hand....

On a serious note I don't think there is really a good trick to remebering them. After you work with them for a while they just stick.

There are much harder things to memorize in the CCNA than this, in my opinion.
