❓ FAQ — Math Tutoring in Preparatory Classes in 2026
Financial Questions
Does the French tax credit really reduce the cost of CPGE tutoring?
Yes, significantly. The Crédit d'impôt pour l'emploi d'un salarié à domicile covers 50% of qualifying at-home tutoring costs for eligible French households. For example, Groupe Capitole charges €59–75/hour gross, reducing to approximately €30–37/hour net. Les Sherpas at-home sessions reduce from €14 to approximately €7/hour net. Eddmon additionally offers immediate advance payment of the credit. Full eligibility rules are on service-public.fr.
What budget should I plan for private math lessons in preparatory classes?
Net hourly rates after tax credit range from approximately €7/hour (Les Sherpas) to €37/hour (Groupe Capitole upper range). Annual programme pricing runs from €2,990 (Optimal Sup Spé) to €3,490 (Les Cours du Parnasse full year). The appropriate budget depends on the level of specialisation, the competitive examination target, and the intensity of support required. Most families achieve effective CPGE-level support between €14 and €27/hour net.
Are intensive holiday math courses worth the investment during preparatory classes?
Yes. Holiday intensive courses allow students to review a challenging chapter in analysis, integration or probability; prepare for a concours blanc (mock competitive examination); or rebuild methodological confidence over a concentrated period. MyPrepa, Groupe Capitole, Les Cours du Parnasse and Acadomia all offer structured intensive formats specifically calibrated for CPGE competitive examination schedules. When used to address a specific identified gap, they provide a high return on a limited time investment.
Methodology and Platform Comparisons
Why do Les Sherpas hold the top position in this ranking?
Les Sherpas provide the best overall balance across all evaluation criteria: certified teachers (including Polytechnique and CentraleSupélec graduates), the structured Méthode Sherpas® addressing content, study method and exam technique, full format flexibility (online or at home), and the most accessible price point in this ranking (from €7/hour net). Their 93% progression rate and documented +4.36 point average grade improvement provide objective evidence of consistent student outcomes across all academic levels.
Is MyPrepa suitable for all preparatory-class students?
No — MyPrepa is specifically designed for ECG (Économique et Commerciale voie Générale) preparatory students targeting the competitive examinations of HEC (Hautes Études Commerciales), ESSEC, and other top business schools. Its flipped classroom model, mental coaching, and exam-focused intensity are well-matched to ambitious ECG profiles. It is not suited to MPSI, PCSI or other scientific tracks.
Is a specialist CPGE platform better than a generalist tutoring platform?
It depends on the student's track and examination target. A generalist platform like Les Sherpas offers flexibility, cross-subject coverage, and accessible pricing — effective for foundational support and methodology coaching across all CPGE tracks. A specialist platform like MyPrepa or Optimal Sup Spé delivers higher examination-specificity for defined targets. Groupe Capitole combines both dimensions through examiner-led individualised instruction. The right choice is determined by the student's examination calendar and the specific mathematical domains requiring reinforcement.
What criteria should I compare before choosing a CPGE math tutoring platform?
Evaluate: (1) teacher credentials relative to your CPGE track — Agrégé, examiner, or Grandes Écoles graduate; (2) track specificity — ECG, MPSI/PCSI, or generalist; (3) trial lesson availability; (4) net hourly rate after tax credit; (5) digital infrastructure — interactive whiteboard with LaTeX support, session replays, mock examination marking; (6) commitment terms — hourly, package, or annual programme. Our 6-point checklist above summarises these criteria in an actionable format.
Student Needs and Warning Signs
How do I know whether my child needs math tutoring in preparatory classes?
Key indicators in a CPGE context include: grades that have declined across two or more consecutive assessments; persistent difficulty keeping pace with the syllabus advancement in analysis or linear algebra; loss of confidence in oral examination settings (colles); or systematic errors in competitive examination-style problems that are not corrected between sessions. In both scientific and ECG preparatory classes, a small methodological weakness can compound rapidly under the accelerated pace of the programme. Targeted academic coaching is most effective when initiated at the first sign of persistent difficulty — before gaps reach the concours calendar.
Should I prioritise online or at-home math lessons in preparatory classes?
Online instruction integrates more easily into the demanding CPGE timetable — no travel time, flexible scheduling, and access to platforms with session replays (Cours des Grands, MyPrepa LiveClass). At-home sessions suit students who benefit from a physically supervised environment and direct human presence. Les Sherpas and Complétude offer both formats within a single arrangement, making it straightforward to test and adjust based on the student's response.
What is the best option if my child is targeting a highly selective school?
For strong ECG ambitions targeting the top business-school competitive examinations (HEC, ESSEC, EDHEC), MyPrepa provides the most examination-calibrated coaching in this ranking. For highly selective engineering school concours on MPSI/PCSI tracks (École Polytechnique, CentraleSupélec, Mines-Ponts), Optimal Sup Spé maintains a consistent track record. For students requiring premium individualised instruction with active examiner insight across any track, Groupe Capitole is the premier choice. Les Sherpas remain a strong complement for foundational methodology support alongside any of these specialist options.
