Computer Science (NSI) 12th Grade Revision Sheets
Review Terminale specialty Computer Science (NSI) for the bac. The curriculum covers advanced data structures, algorithms, databases, and hardware architectures, with both written and practical exams.
Computer Science (NSI) curriculum in 12th Grade
The Terminale specialty NSI curriculum deepens fundamental computer science concepts. Data structures cover stacks, queues, binary trees, binary search trees, and graphs. Recursion is studied in detail with recursive algorithm programming (merge sort, tree traversal). Relational databases introduce the relational model and SQL (queries, joins, aggregation). Hardware architecture covers systems on chip, routing protocols, and communication security. Object-oriented programming completes the curriculum with classes, inheritance, and encapsulation in Python.

Tips to succeed in computer science (nsi) 12th Grade
Code regularly in Python to master data structures and recursion before the bac.
Practice writing complex SQL queries (joins, subqueries, aggregation) on paper as in the exam.
Prepare the practical exam by redoing past year papers: it represents a significant portion of the grade.
Draw data structures (trees, graphs) to better understand traversal and search algorithms.
FAQ — Computer Science (NSI) 12th Grade
What programming languages are needed for Terminale NSI?
The main language is Python, used to implement data structures (stacks, trees, graphs), recursive algorithms, and object-oriented programming. SQL is also essential for the relational databases section. Basic knowledge of HTML/CSS and JavaScript is helpful for the web component. On the exam, programming exercises are exclusively in Python.
How is the NSI bac exam structured?
The NSI exam includes a 3-hour 30-minute written part with programming, algorithm, and database exercises, and a 1-hour practical exam on a computer. The written part typically has 3 independent exercises covering different chapters. The practical exam involves solving two Python programming exercises, one often related to data structures or recursion.
Are data structures difficult in Terminale NSI?
Data structures (stacks, queues, trees, graphs) are the core of the Terminale curriculum and require a good understanding of abstract concepts. The key is practicing Python implementation: create your own classes for each structure, implement operations (push, dequeue, insert, traverse), and test them with examples. Traversal algorithms (BFS, DFS) and binary tree search are must-know for the exam.
