Organize your vocab list: The best way to approach a large task like memorizing dozens of words for a test is to break it down into smaller parts. Starting at the top of your list, count off 15 words and draw a line. Continue this process until the whole list is broken up into 15-word sections.
Arrange the words of each section in alphabetical order. Alphabetizing your words makes looking up their definitions in the dictionary much simpler and quicker. Set yourself a goal for getting through these sections, like completing one section per week until test day.
Copy the words from your vocab list into a notebook or a word processor on your computer. Then read the definitions provided in your prep book or your dictionary, and write down the definition in your own words, as it makes the most sense to you. For example:
The prep book reads: "irascible -adj- quick to ire"
In your words: "irascible -adj- easily angered"
Build your sentences: Random sentences that use a vocab word properly won't necessarily help you remember the word's definition. Instead, associate each word with a character or event in one of your favorite books or movies. For example:
Random sentence: "The grumpy grandpa is irascible when kids are playing on his lawn."
Your sentence: "The irascible Uncle Vernon would easily get enraged at almost anything Harry did, especially when it put his son Dudley in supposed danger."
This example uses characters from the Harry Potter book and movie series who have very recognizable traits. It also employs a trick that can jog your memory: restating the definition in the sentence. "Irascible" means "easily angered," so your trick is to write that Uncle Vernon "would easily get enraged" to immediately recall the definition.
Study your sentences until you are ready for the test.
