The present perfect tense is used to express an event that happened in the past without specifying the exact time of its occurrence. In this tense we use (have - has) with the main verb in the past participle. Examples I have studied my lessons. He played football. We notice in the first example that we used the auxiliary verb Have because of the presence of the pronoun I, and at the same time we used the third form of the verb (study), which is (studied), because of the presence of the auxiliary verb in the sentence that occurred in the past tense without specifying the time of occurrence of the verb, which necessitated placing the verb here in the present perfect tense.

I am a qualified and experienced mathematics tutor. Graduated from the Free University of Brussels in 2011, I started my career by teaching remedial courses in different schools in Brussels. I then specialized in individual academic support by following educational training at the Harvard Graduate School of Education. I have been giving private mathematics lessons daily for over ten years. The students who follow my private lessons benefit from personalized support. The first session is devoted to an in-depth assessment of the student's mathematical knowledge. The objective is to detect its weak points and understand their origin in order to adapt my courses to its needs. I develop a tailor-made remediation program for each of my students aimed at filling each of their gaps. Over the course of the sessions, the student builds a solid foundation for learning and regains self-confidence. At the same time, I help him acquire a work methodology that allows him to gradually become autonomous in his studies. I have a perfect knowledge of the mathematics program of the College and the High School (from the Sixth to the Terminale). During my formative years, I studied and developed many techniques that make it easier to learn math. The strength of my pedagogical approach lies in my ability to explain in a simple way everything that the student finds complicated. I am passionate about this job because it gives me the opportunity to guide dropout students on the path to success. It is a real pleasure to see them evolve and come to terms with the fantastic world of mathematics. I provide my private lessons in Limoges (at the student's home) or remotely (online via the internet). My distance learning courses take place on an interactive online whiteboard. This board is specially designed to promote student/teacher interaction on the internet. Thanks to this educational tool, my online courses are as effective as home courses. The student only needs an internet connection and a computer, tablet, or smartphone to take advantage of it.

Mathematics course taught by an engineering graduate with over 14 years of teaching experience in mathematics up to the undergraduate level.
