SUBJECT BAC NSI. The exams for the 2023 baccalaureate in the “digital and computer sciences” (NSI) specialty will take place on March 20 or 21. Here’s what to keep in mind.
[Mis à jour le 9 mars 2023 à 15h41] NSI’s specialty written exams are fast approaching. On March 20 or March 21, 2023, depending on your invitation, the seniors who have chosen this specialty will have to work on the table during the writings, which will count for 12 points of the final mark, a significant test. This article contains last year’s tests which will allow graduates to train as much as possible so as not to be destabilized on D-Day.
In three hours and thirty minutes, candidates will have to choose from three of the five exercises that will make up the test. It is their knowledge of programming and the operating system that will be put to the test and which should enable candidates to answer all questions, whether they relate to data processing, mastery of algorithms or programming. . Digital and computer sciences also have a technical aspect. This test will thus be supplemented by a practical part, the date of which has not yet been communicated by the Ministry of Education.
What were the candidates assessed on during the NSI 2022 baccalaureate test? The topics have been made public by the Ministry of Education and are available in full below, thanks to our partnership with Studyrama.You can discover below the details of the problems and exercises offered to NSI candidates.

This year the test will only cover the courses covered in the final year, said the Ministry of National Education.
Answer keys for the 2022 “Numerical and computer science” test are available below thanks to our partner Studyrama. They allow candidates to practice as well as possible and to test themselves before the tests of this year 2023.

Of the six topics that make up the NSI curriculum during the school year, only five can fall on the day of the exam. Five exercises are proposed to the written candidate: they can relate to any chapter of these five themes. On D-Day, the high school student must choose three exercises from the five to choose from, depending on what he has studied the most in class.
In addition, the Ministry of National Education has class the subjects of each subject between the chapters likely to be assessed this year, and those which cannot be assessed in the specialty test, to facilitate revisions. Among these themes you will find in your exercises:
- Data structures
- Data base
- Hardware architectures, operating systems and networks
- Languages and programming
- Algorithmic
Five sections divided into 2 to 4 chapters
Data Structures topic
- Data structures, interface and implementation
- Vocabulary of object programming: classes, attributes, methods, objects
- Lists, stacks, queues: linear structures. Dictionaries, index and key
- Trees: hierarchical structures. Binary trees: nodes, roots, leaves, left subtrees, right subtrees
Databases section
- Relational model: relation, attribute, domain, primary key, foreign key, relational schema
- Relational database
- SQL language: queries for querying and updating a database
Topic Hardware Architectures, Operating Systems, and Networks
- Management of processes and resources by an operating system
- Routing protocols
Languages and programming section
- Recursion
- Modularity
- Development of programs. Bug management.
Algorithmic section
- Algorithms on binary trees and on binary search trees
- “divide and conquer” method
The NSI test has been fixed, like all the other specialty education exams, in March. The NSI written test was scheduled on Monday March 20 and Tuesday March 21, 2023 of 2 p.m. to 5:30 p.m. in metropolitan France and Mayotte. The test will take place earlier in the the DROM-COM, from 9 a.m. to 11:30 a.m. The candidates had 3h30 to pass these tests, knowing that the subjects are different depending on the day of the convocation. The date of the practical part is not yet communicated.
The NSI specialty test is divided into two parts. The first is written and the second is practical. For writing, which counts for 12 points out of 20 in the evaluation of the subject, the candidate must choose three exercises that he wishes to deal with out of the five proposed in all. He has 3h30 to answer the three chosen exercises, knowing that each of them is worth 4 points. For the practical part, which can bring back up to 8 points out of twenty, it is a question of solving two exercises on computer in one hour of allotted time.
For the content of the test, one of the two exercises must relate to the main entries in the programs. In all cases, this test assesses the technical skills of the candidates on the subjects studied during the year.
A priori, the results of the Numerical and computer sciences specialty test will be available on 4th July, at the same time as the results of the other tests (French, philosophy and major oral). The fact that specialty courses are evaluated one month earlier does not affect the publication of the results.
