To study for the roots test, I suggest that you make flash cards with all the roots.
To study for the spelling part, break the word down so that you find the roots in it. You know that the root part will be printed on the test, so study the part that goes along with the root. If a word is made up of two roots put together, don’t focus on that word as much while you are studying.
When taking the vocabulary part of the test, look for words in the definition that are part of the meaning for the root. If you know all the roots and meanings, the test is much easier. The bottom part of the test is extra credit. If you do not have time to study for that part, simply put A’s all the way down so that you will get at least one extra credit point.
