Create a flash card for each vocabulary word you need to know; write the Spanish word on one side and the English word on the other. 3x5 index cards work well because their thickness prevents you from seeing through to the other side.
Create a separate set of flash cards for verb conjugations. On one side, write the base verb and definition ("hablar: to speak"). On the other side, write the six conjugations. If you were studying the present tense, you would write "yo hablo," "tú hablas," "él habla," "nosotros hablamos," "vosotros habláis," and "ellos hablan."
Run through each set of flash cards repeatedly--repetition is your friend. Start out slowly to allow for mistakes; only stop when you can rush through the flash cards and identify everything correctly.
Shuffle the flash cards periodically. You want to make sure you're actually learning the words and not just the order.
