1
Create associations. For each element, memorize a short slogan, story or fact that is related to the metal you need to memorize the symbol for. For example, Argentina was named after the metal silver (Argentum -- Ag) because when the Spanish landed there, they thought that the country had lots of silver.
Sometimes, you might make something funny to remember the element -- for example," 'EY! YOU! Give me back my GOLD!" could help as well since the symbol for gold is Au.

Go for mnemonic devices. That means you'll be using words to associate with each element. They often come in strings or rhymes. Lilly's NAna Kills RuBbish CreatureS FRanticly is an example of a mnemonic device to help remember the alkali metals.
Ignore the easy ones. You're probably pretty confident that hydrogen is "H." Concentrate on the ones that are giving you grief. Here's an example: Darmstadtium is "Ds," right? If you want a mnemonic for that one, try "DARN! STATS for my game were all lost on my Nintendo 'DS' because the power went out!".
