What is SNT in the French curriculum?

SNT stands for Sciences Numeriques et Technologie, digital sciences and technology. It is a compulsory subject in Seconde, the first year of lycee, taught in every AEFE school. It covers how the internet works, social networks, personal data, digital photography and an introduction to Python programming.

Is SNT useful if my child does not want to study computer science?

SNT counts toward the lycee marks and lays foundations useful in every stream: understanding data, social networks and digital privacy. Above all it prepares the NSI speciality in Premiere for those who choose it. A good start in SNT is a real advantage the following year.

Q: My child has never programmed, is SNT accessible?

Yes, SNT is designed for complete beginners. The introduction to Python is very gradual: printing text, simple calculations, using variables. The syllabus does not ask for command of Python, only for understanding its foundations. With a good start, most students find it more accessible than they feared.

Q: How many sessions are usually needed in SNT?

To catch up or unblock a specific point, 2 to 4 sessions can be enough. For follow-up across the year, one session every two weeks is often sufficient. I always start by assessing the student's level and propose a plan matched to their goals and timetable.

What SNT is

Sciences Numeriques et Technologie is a compulsory subject in Seconde in the French curriculum, taught in every AEFE lycee in Montreal. Its aim is to give students solid digital literacy: understanding how the internet works, social networks, personal data, digital photography and basic programming.

SNT is not a speciality and does not count toward the Baccalaureate in the way the specialities do. That said, it introduces ideas that come back in NSI in Premiere and Terminale and in any scientific or technical career.

For many students it is their first encounter with programming. Good support in SNT means starting well, avoiding blockages and building sound habits of reasoning.

The themes of the SNT syllabus

The internet and the Web

TCP/IP, HTTP and DNS protocols

Recommendation algorithms
Collecting and exploiting data
Disinformation and filter bubbles

Python programming

Variables and simple types
Conditional statements
for and while loops
Functions and parameters
First lists and arrays

Digital photography and embedded computing

Pixels, resolution, colour encoding
Image compression (JPEG, PNG)
Sensors and microcontrollers
Connected objects, the internet of things
GPS and digital mapping

Why this tutor for SNT

SNT is often taught by teachers who are not computer science specialists. A tutor with real training in computing can explain the ideas in depth, answer the questions students actually have, and give the syllabus meaning rather than vocabulary.

I hold a B.Sc. in Computer Science, Finance and Mathematics from McGill and an M.Sc. in Applied Computer Science from Concordia, with 10 years of tutoring in Montreal. For students considering the NSI speciality in Premiere, a good start in SNT is a genuine advantage.

SNT: a first step into digital literacy

SNT is routinely underestimated by students and families. It is nonetheless the subject that introduces the digital ideas every citizen and every future professional will meet: how the internet works, what an IP address is, why personal data has value, how a recommendation algorithm shapes what you see online. These are important questions, not trivia.

For students considering the NSI speciality in Premiere, SNT is a springboard. Students who genuinely understood SNT, rather than memorising it, arrive in NSI with a concrete advantage: they already have basic Python reflexes and they understand networks and data. The first term of NSI is far smoother.

My method in SNT is the same as in NSI: build the reasoning before giving the definitions. We first understand why HTTP differs from HTTPS and what that means in practice for security, before learning the definition. That kind of learning is remembered better and reused in other contexts.

Free corrected exercises for SNT

An exercise set in the format of a class test: 10 questions marked out of 100, a first part on the fundamentals and a harder second part, with a full worked solution for every question. The internet and Web theme is treated in full, from protocols and IP addressing through to HTML and HTTP requests. A revision sheet per theme gives the exact vocabulary expected in a test, the diagrams to be able to redraw, and the classic confusions: an IP address versus a MAC address, the Web versus the internet, a sensor versus a piece of data. Free, no sign-up, written in French.
