Subject of the 2022 baccalaureate, NSI specialty: the Digital and computer science test is for today

NSI PROOF. The 2022 baccalaureate begins this Wednesday, May 11 and among the specialty tests passed during this first day of tests include Digital and Computer Science (NSI). What subject can the candidates be confronted with?

[Mis à jour l 11 mai 2022 à 10h46] The baccalaureate specialty exams 2022 begins this Wednesday, May 11 and candidates who have opted for the Digital and Computer Science (NSI) specialty will discover their subjects today or tomorrow depending on the calendar. This Wednesday, the NSI event is scheduled from 2 p.m. to 5:30 p.m. During these three and a half hours, candidates for the baccalaureate 2022 must answer written exercises based on their knowledge of programming and the operating system. This test will be completed by a practical part, the date of which has not yet been communicated by the Ministry of Education.

The test Digital and computer science has existed since the implementation of the baccalaureate reform: it is one of the twelve specialty subjects that first and final high school students can choose to follow. To appeal to high school students who are comfortable with their computers and the world of data, the scope of the fields studied has been widened, offering the possibility of deepening the achievements of the course in Digital and Technological Sciences, the subject common to the class. of Second.

The NSI specialty is vast, between data processing, mastery of algorithms and programming. Digital and computer sciences also have a technical aspect. For the 2022 baccalaureate, the principle of the choice by the candidate of the three exercises that he will deal with out of the five proposed is maintained. Given the diversity of topics studied during the year, it can however be difficult to know what to expect for certain candidates.

the Wednesday May 4, the high schools passed the Digital and Computer Science specialty test. They had 3.5 hours to perform three exercises to choose from among the five proposed. What were the 5 possibilities?

  • Exercise 1: the themes to be mobilized were programming and recursion. The high school students had to define a “shorten” function in Python that acts on a string of characters.
  • Exercise 2: This exercise focused on hardware architecture, scheduling and Boolean expressions. The candidate must work on waiting lists according to the order of the devices.
  • Exercise 3: This is an exercise on databases, the relational model and the SQL language. The candidates studied a system for collecting browsing data from a website, in order to study the profiles of visitors.
  • Exercise 4: This exercise focused on data structures and stacks. We were trying to sort elements in ascending order.
  • Exercise 5: it was about algorithms and binary trees. The candidate had to draw a binary tree, determine its height with an algorithm and number the nodes.

Of the six topics that make up the NSI syllabus, only five are likely to fall on exam day. Five exercises will be proposed to the written candidate: they can relate to any chapter of these five themes. Like last year, on D-Day, the high school student will have to choose three exercises from the five to choose from, depending on what he has studied the most in class. It’s a little complicated, but it leaves you with a wide range of choices, and the possibility of juggling between the themes according to your knowledge. The objective is not to penalize those whose course follow-up has been disrupted due to the health crisis.

In addition, the Ministry of National Education has classified the subjects of each subject between the chapters likely to be assessed this year, and those which are not assessable in the specialty test. Automatically, an entire theme “History of Computing – Theme 1”, as well as several chapters (within the five remaining themes) may be slightly excluded from the candidates’ revisions. However, it is preferable not to ignore them completely: the subjects can be cross-cutting, certain knowledge can help candidates in front of their copy. Discover the five themes on which you are likely to come across on D-Day:

  • Theme 2: Data structures
  • Theme 3 – Databases
  • Theme 4 – Hardware architectures, operating systems and networks
  • Theme 5 – Languages ​​and programming
  • Theme 6 – Algorithms

Within the five themes, on which chapters can you be assessed?

Theme 2 – Data structures

  • 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.

Theme 3 – Databases

  • Relational model: relation, attribute, domain, primary key, foreign key, relational schema
  • Relational database
  • SQL language: queries for querying and updating a database

Theme 4 – Hardware architectures, operating systems and networks

  • Integrated components of a system on chip
  • Management of processes and resources by an operating system
  • Routing protocols

Theme 5 – Languages ​​and programming

  • Recursion
  • Modularity
  • Development of programs. Bug management

Theme 6 – Algorithms

  • Algorithms on binary trees and on binary search trees
  • Divide and conquer method

The NSI test was normally to take place like all the other specialty education exams in March, but the Ministry of National Education has decided to postpone the series of tests to May to prevent certain candidates from being penalized. by the consequences of the Covid-19 epidemic on the school system. It is therefore between May 11 and 13 that the tests are held. The NSI written test is organized on Wednesday 11 or Thursday 12 May from 2 p.m. to 5.30 p.m.according to the first details of theStudent. You will have 3h30 to pass these tests, knowing that the subjects will be different depending on the day of your convocation. The date of the practical part is not yet communicated, but we will make sure to inform you as soon as possible.

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 will have 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 will be a question of solving two exercises on computer in one hour of allotted time. For the content of the test, all we know for the moment is that one of the two exercises will focus on the predominant entries of the programs. In any case, this test will assess your technical skills on the subjects studied during the year. We will let you know the details of this practical part as soon as possible.

A priori, the results of the Digital and Computer Science specialty test will be available on July 5, 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.
