----End Copy and Paste----

The student should Copy and Paste the above into a Notepad or Word document and print it. The student should then read a few definitions of each term and write out the acronym spelled out and its definition on the back of a 3x5 card with the acronym on the front of the card. Then practice by shuffling your cards, then spell each one out and then define it. Then flip to the next card. When the student can go through the deck without difficulty a large part of the final exam is in the bag!
