I'd like to start by greeting everyone who is reading this and then briefly discuss the teachings I'm providing. Going to medical school is a major step, and while becoming a doctor may have been a big dream of yours, things unfortunately didn't turn out the way you had hoped. You didn't receive what you eagerly want following your bac. I'm here to tell you that earning your bac is just the first step on a longer journey. You have another opportunity to fulfill your lifelong ambitions. What role do I play in this? as someone who has been in your position and ultimately obtained what I want. We will have a customized plan that fulfills your needs, we will correct any unsuccessful methods and build new ones, and I will lead you through the program at every stage.

This is the ultimate executive function and study skills coaching program that utilizes Artificial Intelligence as a personalized assistant.

Designed specifically for students with Special Educational Needs (SEN), including those with challenges in organization, focus, and information processing. This course provides real, measurable tools for academic autonomy.

We move beyond basic homework help. We treat the AI as a co-teacher to manage specific learning barriers:

The AI study buddy: Students learn to use generative AI (e.g., ChatGPT) ethically as a powerful organizational assistant. They master using it to summarize dense notes, break down complex science paragraphs into simplified concepts, or structure large projects into manageable steps.

Executive function tool integration: We focus on integrating AI-enabled planning apps and task management systems to assist with time management, scheduling, and project sequencing—skills essential for students with ADHD or organizational difficulties.

Personalized remediation: We leverage generative AI's power to create instant, personalized learning aids—for example, quickly generating visual study guides, mind maps, or specific practice quizzes tailored to the student's current school curriculum and unique learning style.

The Goal: To build confidence, independence, and accountability, allowing the student to navigate their schoolwork more effectively and rely less on parental or teaching support.

Why this program is premium: your investment covers the specialized pedagogical planning required for this complex integration:

It requires extensive preparation to tailor AI prompts and tools to the student's specific SEN profile (e.g., Dyslexia, Dyscalculia, ADHD).

It includes the creation of detailed progress reports and recommended toolkits for parents, ensuring strategies are consistent at home and school.

I offer comprehensive academic tutoring in Sciences (Biology, Chemistry) and Languages (Spanish, French). I am fluent in Spanish and French and can provide immersive language practice or explain complex science concepts in your preferred language.
My goal is not just to teach the material, but to help students build confidence and effective study habits. My approach is:
Customized: I adapt my lessons to you/ your child's specific learning style, whether you are a visual learner or need hands-on practice.
Experienced: I have experience working with diverse age groups, from teaching Creative Dance to children (ages 4-7) to virtual tutoring for highschool students, and training research assistants in clinical settings.

Whether you need help preparing for a Chemistry exam, writing an essay, or practicing conversational Spanish, I provide a supportive and engaging environment to help you succeed. I have thorough experience in high-level experience and am a strong believer that with the proper organizational and strategic planning, anyone can succeed!
