- Cluster prerequisites are a minimum requirement for consideration by cluster faculty.
- Overall grades in math/science courses are strongly considered over GPA.
- Honors and AP courses are recognized as more difficult.
- Average applicant GPA is 3.8 unweighted.
- To calculate unweighted GPA please visit this Unweighted GPA Calculator.
- All essays are read, all applications reviewed. Faculty read to determine the applicant's motivation and what they want out of their COSMOS experience. This is the student's opportunity to convince faculty that they should be chosen for this cluster.
