Computer Science — Grade 11

American Curriculum · Ages 16-17

Eleventh grade computer science moves into data structures and applied development. Students work with stacks, queues, linked lists, trees and hash tables, analyze algorithm efficiency using Big-O notation, and build multi-file applications.

Many courses at this level introduce databases and SQL, version control with Git, and full-stack web development. Students taking AP Computer Science A in this year cover the object-oriented Java syllabus and its Create-style free-response demands.

Key topics covered

• Data Structures — Stacks, queues, linked lists, trees and hash tables.
• Algorithm Analysis — Big-O notation and comparing the efficiency of approaches.
• Object-Oriented Design — Designing class hierarchies for a real, multi-file application.
• Databases & SQL — Relational design, keys, and select, insert, update and join queries.
• Web & Application Development — Front-end and back-end development and connecting the two.
• Version Control — Git workflow, commits, branches and collaborating on code.
