Second day of specialty tests for the 2023 baccalaureate this Tuesday, March 21. A new burst of physics-chemistry subjects will be unveiled in the afternoon. Discover yesterday’s topics and fixes and still probable topics…
[Updated March 21, 2023 at 10:47 a.m.] The physics-chemistry baccalaureate exam enters its second act this Tuesday, March 21, 2023. While a first round of subjects was unveiled yesterday for a first group of high school students, a second series of tests is scheduled from 2 p.m. for this specialty, which will now be anticipated, starting in March.
Physics and chemistry, if it is one of the major specialties among the approximately 536,000 baccalaureate candidates this year, is nonetheless one of the most difficult. In the subjects unveiled yesterday, three exercises were offered to candidates for the general baccalaureate.
The first subject invited candidates to study the astronomical telescope of Huygens and in particular to compare his observations of Saturn and its rings with those of Galileo. Then came the study of the movement of the satellite Titan, again based on Huygens’ observations.
The second exercise of the physics-chemistry test focused on the study of banana aroma, with comparison of several protocols for synthesizing this chemical species in the laboratory, but also to determine which synthesis is the most eco-friendly. -responsible.
A third exercise aimed to study a sachet of medicine containing acetylsalicylic acid, the scientific name of aspirin, well known since the beginning of the 20th century as an analgesic (painkiller) and antipyretic (against fever) active ingredient. . Discover the details of the physics and chemistry subjects and answers, for the general baccalaureate but also for the technological baccalaureate, below.
The subjects of the physics-chemistry specialty test may relate to one of the four main themes covered in the Terminale program: “constitution and transformation of matter”, “movement and interactions”, “energy: conversions and transfer or “waves and signals”. While it is advisable to avoid dead ends during revisions, the specialized site Digischool, which has worked in collaboration with teachers, estimates that the subject of physics and chemistry in 2023 could emphasize:
The first subjects unveiled on Monday March 20 confirm a number of these predictions. Will the other topics be discussed this Tuesday? We must not rule out the other possibilities of subjects such as the evolutions and directions of evolution of systems (oxidant-reducer or acid-base), wave phenomena or even the chapter on images and light. All subjects listed by the Ministry of National Education can indeed fall on the day of the test.
The baccalaureate exams in French high schools abroad or in French Polynesia, taken a few days before those in mainland France, can provide other clues to the physics-chemistry specialty.

Physics and chemistry subjects for the 2023 baccalaureate in French Polynesia:
Don’t forget that in addition to the courses, certain specific notions or those related to several chapters are essential, as well as formulas, physical or chemical reactions, etc. As well as methodologies to demonstrate scientific reasoning. Moreover, it is advised to always write the literal formulas before carrying out its calculation, it is a detail of presentation which can make gain points easily.
The organization of the physics-chemistry test, like the rest of the specialty tests anticipated from March, is a first, since since the baccalaureate reform started in 2018, the new baccalaureate has never yet been fully organized, Covid obliges.
Monday March 20 like Tuesday March 21, 2023, the candidates have 3h30, from 2 p.m. to 5:30 p.m., to answer all the questions. For the physics-chemistry specialty, the written test is only the first part of the exam, the second is a practical test organized between March 23 and 31.
But the table exam represents 80% of the final grade in physics and chemistry, which has a coefficient of 16 in the bac average. And for this test, several notions must be mobilized in each of the three independent exercises.
After the written physics-chemistry test on March 20 and 21, the practical test will last one hour and will be held for all candidates between March 28 and 31 according to the times of the invitation. On the subject side, no exercises common to all candidates but a certain number of assessment situations among those available on the national subject bank of National Education. However, the ministry specifies a few scientific manipulations on which candidates cannot be assessed:
At the time of the examination, the candidate draws lots for an evaluation situation “from a subset, renewed every half-day, of at least two predominantly physical evaluation situations and two predominantly physical evaluation situations. chemistry,” according to the ministry. He then has one hour to perform the requested manipulations.
If the specialty exams are held several months before the written philosophy, French or major oral exams, the results will be published at the same time for all baccalaureate exams, i.e. Tuesday, July 4, 2023. As a reminder, the exam of physics-chemistry being composed of two parts, the final mark is obtained by multiplying by 0.8 the mark of the written test and by 0.2 that of the practical test.
