What can we do to remember that "." is for classes, and "#" is for ID's? is there some kind of acronym or saying?
What helps you identify between the two? What I have come up with, Classes are related to school and Periods (".") are related to school as well. Thanks!

Other than Dave's answer the only other thing I can recommend is practice and repetition. Over time, it will stick in your memory! :-)

To be honest, I have never heard of any time of saying or acronyms for this.
I guess one way you can remember at least the # is using the concept of twitter hashtags, where you can have only unique hashtags. But other than that, this is just one of those things you need to memorize, and to be quite honest, it is very simple to remember, you just have to use them more often so that it gets ingrained into your memory.
Thanks for the help. I'm using school metaphor to remember this in the future. In middle school, we used to call our classroom's Period. So for CLASS I related it to PERIOD. I like the hashtag reference from Dane, thanks for the tip.
