Since the high school reform, the S baccalaureate no longer exists. Students applying for BCPST preparatory classes come with very varied combinations of specialties. Some profiles, far from the traditional scientific path of the past, still achieve excellent results in preparatory classes and in the life sciences competitions.
Terminal specialties and BCPST prep: what juries really look at
Are you wondering if your combination of specialties is sufficient to enter a good BCPST prep? The answer depends less on the label of your baccalaureate than on three concrete elements in your application.
Admission committees primarily look for SVT maintained as a terminal specialty. This is the disciplinary marker of the field, indicating a genuine interest in life sciences. Next is the level in mathematics: a complete specialty is an asset, but the complementary math option is accepted by most high schools. Finally, physics-chemistry taken at least in the first year completes the expected foundation.
This triptych is not a copy-paste of the old S baccalaureate. A student who kept SVT and complementary math in their final year, while having followed a literary or economic specialty in the first year, can very well submit a solid application. To better understand the ranking of BCPST preparatory classes 2026, one must indeed look beyond just the scientific averages.
The BCPST admission guides remind us: no text sets a minimum average for applying. It is the consistency of results, progress over the terms, and teachers’ evaluations that determine whether an application is accepted.
Balanced profiles in BCPST: why French and languages matter
The BCPST prep is not just about sciences. The French-philosophy and living language exams represent a significant part of the coefficients in the agro-vet competitions. A student who writes well and masters English has a real advantage over a purely scientific but weakly written profile.
This is where atypical profiles excel. A candidate who studied humanities, literature, and philosophy in the first year, before refocusing on SVT and math in their final year, arrives in prep with a writing proficiency that two years of khôlles cannot compensate for.
What agro-vet competitions value in writing
The dissertation and synthesis exams in the competitions test the ability to structure reasoning and mobilize cultural references. Correctors quickly distinguish a candidate who knows how to argue from one who merely applies technical knowledge without a guiding thread.
Literary subjects are therefore not a handicap in the previous path: they become a lever. Several preparatory classes even state on their Parcoursup sheets that the grades in French and LV1 are among the discriminating criteria when reviewing applications.
Reorientation towards BCPST prep: a successful path
Another profile that is progressing in BCPST admissions is reorienting students. Recent Parcoursup data shows a notable increase in these candidates in selective programs, including in scientific CPGE.
Some high schools now welcome more than 10% of admitted students from a reorientation. Lycée Jacques-Prévert in Boulogne-Billancourt, for example, shows about 13% of reorientations among its BCPST admits. These students often come from a first year of a biology or chemistry degree, or even from PASS/LAS.
Why these profiles succeed in preparatory classes
A student who reorients after a semester or a year in higher education has already experienced the university rhythm. They know how to organize their personal work, manage exam pressure, and identify their weaknesses. In prep, this maturity largely compensates for the one-year gap.
The motivation demonstrated by a voluntary reorientation carries significant weight in the evaluation of applications. Committees see it as a thoughtful choice, not a fallback option. Provided that the results in higher education are satisfactory and that the project towards careers in life sciences is coherent, these applications pass the selection filter very well.
Parcoursup criteria in BCPST: beyond raw grades
The rankings of BCPST preparatory classes published each year are based on various indicators. However, for a candidate, understanding what Parcoursup values in their own application is more useful than comparing integration rates between high schools.
Here are the elements that concretely distinguish a successful application from a rejected one:
- The coherence of the choice of specialties with the BCPST field, particularly the presence of SVT in the final year and a foundation in mathematics
- The consistency of grades throughout the terminal cycle, with particular attention to progress between the first and final years
- The qualitative evaluations from teachers, indicating intellectual curiosity, work rigor, and the ability to delve deeper
- The motivation letter (motivated training project), which must connect the previous path to a concrete project towards the agro-vet competitions, ENS, or G2E
An application with decent grades but marked progress and glowing evaluations will often be preferred over an application with slightly higher but stagnant averages and lacking depth.
Numbers and selectivity: a data to be put into perspective
BCPST preparatory classes have very variable numbers, ranging from fewer than ten students to several dozen per class. This disparity makes comparisons of integration rates tricky. A small structure with two admits to AgroParisTech will show a spectacular percentage, while a large high school sending fifteen students to the same competition may appear less effective in proportion.
Reading a ranking without considering the size of the cohorts leads to misleading conclusions. The raw integration rate says nothing without the number of students presented.
Ultimately, the profiles that succeed in BCPST share a common point that has nothing to do with the old S baccalaureate: a genuine interest in life sciences, a capacity for regular work, and a file that tells a coherent trajectory. The combination of specialties opens the door, but it is the coherence of the path that crosses it.
