General Subjects: French, Mathematics and Applied Sciences
French
Master reading comprehension, grammar (agreement of the past participle, use of the subjunctive after expressions of necessity), vocabulary, and written expression. Know how to summarise a text, write a formal letter, and answer comprehension questions. Trap: the past participle agrees with a preceding direct object, not with the subject when the auxiliary is avoir.
Mathematics
Know arithmetic (proportions, percentages, rule of three), geometry (areas of rectangles, triangles, circles, and volumes of cylinders), and basic statistics (mean, median, mode). Understand unit conversions (1 ha = 10,000 m², 1 t = 1,000 kg). Trap: confusing units - a common error is mixing metres and hectares.
Applied sciences
Understand basic physics (mass, weight, density, pressure), chemistry (acidity, pH, fertiliser composition), and biology (plant and animal cell, photosynthesis, respiration). Know the role of microorganisms in soil fertility and fermentation.
Worked example
A circular garden has a radius of 7 m. Area = π × r² = 3.14 × 49 ≈ 153.9 m². If a farmer applies 200 g of fertiliser per m², total fertiliser = 153.9 × 0.2 kg ≈ 30.8 kg. Always write the formula, substitute, and state units.
