As a dedicated tutor with extensive experience in preparing students for standardized exams such as the SAT, GMAT, and SSAT, I understand the unique challenges that each of these tests presents. My approach is comprehensive and focuses on building a strong foundation in critical areas such as Mathematics, Quantitative Reasoning, Verbal Skills, and Analytical Writing. Each program I develop is tailored to the specific requirements of the exam, ensuring that students are well-prepared and confident on test day.

Having a deep understanding of the test formats and question types allows me to provide personalized strategies that target each student's individual strengths and weaknesses. I believe that every student has a unique learning style, and my goal is to enhance their test-taking skills while improving their time management. By fostering a supportive learning environment, I aim to boost students' confidence and empower them to achieve top scores.

My tutoring sessions incorporate a variety of effective methods, including real exam questions and timed practice tests. This hands-on approach allows students to familiarize themselves with the types of questions they will encounter, making the actual exam feel less daunting. I teach proven techniques for tackling even the most challenging problems, ensuring that students feel equipped to handle any question that comes their way.

One of the key components of my tutoring is helping students develop effective study habits. I provide guidance on creating a structured study plan that maximizes their preparation time and aligns with their personal goals. This structured approach not only keeps students on track but also helps them build a sense of accountability, which is crucial for success.

In addition to academic preparation, I also focus on the psychological aspects of test-taking. Many students experience anxiety leading up to exams, which can affect their performance. I teach relaxation techniques and mental strategies to help manage stress, allowing students to approach their exams with a calm and focused mindset. By addressing both the academic and emotional challenges of test preparation, I equip students with a well-rounded toolkit for success.

Feedback is an essential part of the learning process, and I make it a priority to provide constructive and actionable insights during our sessions. After each practice test, I conduct a thorough review of the results, highlighting areas for improvement while also acknowledging progress. This continuous feedback loop helps students understand their growth and keeps them motivated throughout their preparation.

My commitment to student success goes beyond just teaching content. I aim to inspire a love for learning and self-improvement in each of my students. Many of my former students have gone on to achieve their academic goals, securing places at prestigious universities and programs. Their success stories are a testament to the effectiveness of my tailored approach and the dedication I bring to each tutoring session.

If you're looking to master the SAT, GMAT, or SSAT with confidence, I invite you to book a session now. Together, we will develop a customized learning plan that suits your individual needs, ensuring that you are not only prepared to face the test but also equipped to excel and reach your highest potential. With my guidance and your commitment, we can achieve outstanding results. Let’s embark on this journey to success together!

Hello students! Do you find it difficult to learn science subjects, especially chemistry? This may be because chemistry contains some difficult or complex concepts or terms. If you are one of these, do not worry!! Hello and welcome to you, my students, in the right place to solve this problem through simplifying science lessons, especially chemistry. Through these lessons, we will learn together how to deal with difficult-to-understand matters and terms, because I have extensive experience extending to more than 15 years in conveying complex concepts in a clear, easy and simple way. My goal is to make science and chemistry in general and organic chemistry in particular wonderful and understandable for everyone. As a dedicated teacher, I create an interactive and stimulating learning environment for my students using the latest methods. I am ready to share my passion and guide each student towards excellence and success in the field of science and organic chemistry and in studies in general, as I work as a student advisor in an international institution. In addition, I have excellent communication and presentation skills and am patient and calm when teaching. In addition, I constantly follow up on my students' progress and regularly evaluate their understanding through continuous solution of objective questions, as I care more about understanding than memorization. On the other hand, I also maintain good follow-up with parents. My teaching approach is directed towards achieving the highest results, with a focus on helping students understand and master information.

For university students or master's and doctoral students, I teach the course of natural product chemistry or phytochemistry. In this course, we will learn about the methods of extracting, separating and identifying the chemical form of active chemical compounds (biologically active secondary compounds) from natural sources, such as medicinal and aromatic plants. We will also discuss what is known as chromatography, spectroscopy devices, spectroscopy, mass spectrometry and magnetic resonance analysis. In addition to knowing some important applications of these active materials in various fields, such as the pharmaceutical industry, agriculture, etc. We will also learn the practical methods that are carried out in the laboratory to conduct toxicity, antioxidant and diabetes analyses, etc.

Finally, "for those interested in scientific research" there is a course dedicated to knowing what scientific research is, how to choose a research point, how to write scientific research and how to find the appropriate journal for publication and everything related to this topic.

Experience: About 20 years of practical experience in the field of chemistry, medicinal and aromatic plants and pharmacy with parallel training and private lessons for chemistry curricula.

With my qualifications and experiences, as I hold a master's degree and a doctorate in organic chemistry (chemistry of natural products), in addition to other postgraduate certificates and a doctoral scholarship in pharmaceutical sciences in Belgium from the Erasmus Mundus organization affiliated with the European Union.

•Types of Numbers
•Algebra
•Sets
•Indices
•Fractions
•Functions
•Trigonometry
•Equatioms
•Probability
•Transformations
•Geometry
•Proportions
•Exponential and Decay Curves
•Distance time Graphs
•Mensuration
•Properties of a Circle
•Statistics

Q.Why you will love Maths after the lessons?
1.I will help break down concepts to the level of your understanding.

The authenticity of an exchange. In a society increasingly rooted in a competitive approach, where automated exchanges with Artificial Intelligence cannot replace the need for human interaction, this is precisely what we lack.
As a lawyer by training and an independent legal consultant, creating "Le Droit aux Savoirs" (The Right to Knowledge) is a breath of fresh air. This private tutoring service is aimed directly at students and any adult who needs to overcome difficulties in studying the following subjects: French, Mathematics, Sciences, Philosophy, History, and Languages (English and Spanish). To be clear, these subjects will be studied up to the Baccalaureate level (General/Technological/Vocational).

Moreover, being currently preparing for the entrance exam to the National School of Magistrates and passionate about the beauty of multidisciplinary learning, the school program is being reviewed extremely regularly.

🎓 It is now necessary to elaborate somewhat on my experience:
4 years already dedicated to private lessons (which is significant) via the organization Complétude as well as independently (Law, French, Mathematics, Sciences, History and Languages), and this at all levels (primary, middle school, high school, university students and adults).

Regarding my teaching experience in legal subjects, I invite you to consult my other course offering dedicated to this subject and also published on Apprentus.

👋 What about my teaching approach, you might ask?
Beyond this desire for authenticity, it seems particularly important to dismantle the prejudices that poison the perception of students experiencing difficulties. To ensure the smooth running of this course and so that the student or adult feels as comfortable as possible, it is worth remembering that the foundation of all conversation and understanding remains listening. Listening to one's equal, regardless of age.

💬 Wouldn't you be interested?
Please feel free to contact me by message and I remain available to discuss the frequency of classes and their modalities (in-person in Tours, videoconference and possibility of travel if necessary).

In the meantime, ladies and gentlemen, students or interested individuals, it would be a real pleasure for me to accompany you as best I can on your path to success because, as its name indicates: you all have the Right to Knowledge! 😉
