Online informatics courses for high school and admission to university/college

How to enroll in a course

Vous pouvez vous inscrire à nos cours en ligne à tout moment :

  1. Veuillez nous contacter via le chat sur ce site Web pour convenir à l’avance d’une date de début prévue de vos cours pour un cours en ligne spécifique.
  2. Immédiatement après accord préalable, achetez des cours en ligne spécifiques convenus.
  3. Après votre achat, nous programmerons le début de vos cours comme convenu au préalable et vous donnerons toutes les instructions nécessaires.

Refer to "Purchases and Payments" section (lien) of the "Terms and Conditions" (lien).

Rafraîchir les connaissances et les compétences :

Si une remise à niveau est demandée, nous supposons que vous avez déjà une bonne compréhension du sujet donné et nous nous concentrerons sur la mise à jour de vos connaissances le plus rapidement possible. Vous recevrez des instructions identiques ou plus concises et des exercices moins longs, mais plus avancés. Cela vous permettra d’avancer à un rythme parfois plus rapide et est donc recommandé lorsque les délais sont serrés.

Apprenez avec un tuteur personnel :

Si l’apprentissage avec un tuteur personnel est demandé, nous veillons à ce que le même tuteur dédié suive de près vos progrès dans le ou les cours en ligne spécifiés pour lesquels le tuteur personnel a été demandé. Cela permet un tutorat plus précis, spécifique à l’élève et hautement personnalisé : enseignement, motivation, clarification des concepts et aide au renforcement des apprentissages. Cependant, le tutorat personnel peut se dérouler à un rythme plus lent en raison des problèmes d’emploi du temps auxquels nous sommes confrontés à ce moment-là et n’est donc recommandé que lorsqu’il n’y a pas de délais serrés.

Individual or group courses

Vous pouvez vous inscrire à l’un de nos cours en ligne avec votre propre groupe d’étudiants (par exemple, vos amis, vos camarades de classe, des camarades d’étude aléatoires, etc.) pour suivre ce cours ensemble, ce qui permet de réduire le prix par étudiant de près de la moitié. Plus votre groupe est grand, plus le prix par étudiant est bas, et même un groupe de seulement 2 étudiants (c’est-à-dire vous et quelqu’un d’autre) vous permet d’appliquer une réduction importante. Pour n’importe quel cours, la page que vous consultez actuellement affiche le prix pour un seul étudiant (c’est-à-dire un cours individuel), ainsi que le prix par étudiant du même cours pour votre groupe de 3 étudiants. Au lieu de cela, obtenez cette page avec les prix pour votre groupe de n’importe quel nombre d’étudiants (de 2 à 10) :
