Which Verbal Section Do You Need to Improve the Most?

As an ASVAB tutor, I know the importance of deciding which subtests need the most help in order for people to improve their ASVAB score.  The verbal sections of the text include Word Knowledge and Paragraph Comprehension. When I meet people in my ASVAB, many people need help with ASVAB math and others need more help with the vocabulary and reading sections. The question is which verbal section do you need more help with?
