The Beloit School District is holding up twin sisters as examples of excellence in both learning and leadership.  School officials say Kimberly and Kerilynn Guevara have won full-ride academic scholarships to Brown University.  Brown University says this fall’s incoming class was chosen from the largest applicant pool to date with more than 47,000 students vying for fewer than 1700 spots.  Kimbery and Kerilynn were both in the BACH Academy for Business, Art, Communication, and Hospitality at Beloit Memorial, as well as numerous school clubs and community organizations.  The twins plan to study applied mathematics and economics.
