Talking to students every day, I notice that they are often unaware of how they measure up as an applicant to colleges. Generally, they underestimate themselves. Most students I've met this application season are more competitive than they realize.
The reason students underestimate themselves is that they often think they need a higher GPA and test scores than they actually do. In addition to not knowing the actual requirements they need, they often do not realize the role of other things about themselves that make them good candidates for admission such as student activity accomplishments, volunteerism and employment.
Helping students discover the qualifications they need and appreciate the qualifications they have increases confidence and helps them make realistic plans for themselves.
