When doing a search for information, it is important to think of words to use in the various sources you will be looking at.
For example, you might use the terms:
college education
higher education
university education
colleges
universities
You might want to use a second term also
value
benefits
meaning
results
You should make a list of terms that you will use before starting out. Each source that you consult may employ different words that mean the same thing.
