Absolutely. I used a rhythm mnemonic in middle school to remember pi to 106 digits in middle school, and that was the day of the quiz (it was extra credit in... geometry for some reason). Actually the more you practice these techniques on completely ordinary and mundane things, the easier it becomes when attempting formulae, tables, and graphs. Saving your memory for "important things" will only deprive you of essentially free practice. The periodic table is actually a good place to start as long as you don't overwhelm yourself, so for example start with the names of the elements in order, then the numbers will associate, and you can keep building with recursion. OR you could begin with smaller blocks if you're more comfortable absorbing a lot of different information at once, which can sometimes work much better.
