Keep working on bringing up your grades. In addition, remember that typically colleges and universities do not make admissions decisions based on only one part of the applicant. There are other considerations. The following is just an example of the criteria schools are concerned with.

  • If submitting ACT, the writing section is required

Very important admission factors:
  • Class Rank

  • Standardized Test Scores
  • Academic GPA

Considered:
  • Application Essay
  • Extracurricular Activities
  • Geographical Residence
  • Racial/Ethnic Status
  • Recommendations
  • State Residency
  • Volunteer Work
  • Work Experience
