Preparación para la Liga Estadounidense de Ciencias de la Computación (División Junior, grados 7 a 9)

American Computer Science League (ACSL) organizes team computer programming and computer science contests for K-12 schools, organizations and local groups, led by an adult advisor. The 2023-2024 school year will be our 46th year of continuous operation! Last year, over 500 teams and more than 6000 students in the United States, Canada, Europe, and Asia participated. Out ACSL Elementary division team won one Gold medal, one Silver medal and two bronze medals in 2023; and our ACSL Junior team won one Bronze medal in 2023.

When you join our class you automatically become one of our team members at no cost, we would offer help to register, prepare, and compete in the final contest. 

The ACSL competition is split into four contests, each covering a unique set of concepts. To match the given schedule and give our students the best chance to succeed, we split the course into four parts of three 90 minutes lessons each. The material covered in this course is recommended for motivated students with moderate to extensive mathematical experience. No coding is involved, but the material requires practice and will challenge students academically. Students will take the official ACSL Contest after the third class of each part, and results can be displayed on the ACSL national leaderboard. Students who perform well on a national level may be invited to participate in the ACSL Finals following the end of our course:
