About me

Struggling with Algebra—or stuck below a B? I help students improve grades in weeks, not months. Many of my students start seeing measurable progress within just a few lessons—and major results within 4–12 weeks. Hi, I’m Kelvin. I hold an MSc in Applied Mathematics and a BSc in Physics, with 14+ years of teaching experience helping over 1,500 students worldwide succeed in math. I specialize in IB, GCSE, SAT, ACT, and A-Level Math—guiding students from confusion to confidence with clear, structured learning. 🚀 Real Results (What You Can Expect) Students I’ve worked with have achieved: • Algebra: D → B in 3 months • SAT Math: 520 → 710 • GCSE: Grade 4 → Grade 8 • GED Math: Passed in 5 weeks Most importantly, they gain the confidence to solve problems independently. 🎯 Who I Work Best With I help students who: • Feel stuck, frustrated, or overwhelmed • Need clear step-by-step explanations • Are preparing for important exams • Want to fix weak foundations quickly • Struggle with focus, ADHD, or math anxiety 🧠 ADHD-Friendly Math Coaching I specialize in helping students who find traditional teaching methods difficult. Lessons are designed to be: • Structured and focused • Easy to follow • Engaging without overwhelm This approach works especially well for students with ADHD, learning differences, or low confidence in math. ⚙️ My 4-Step System (Why Students Improve Fast) Every lesson follows a proven structure: Diagnose → Clarify → Practice → Master • Diagnose: Identify exactly what’s holding you back • Clarify: Break concepts into simple, logical steps • Practice: Build confidence through guided problems • Master: Apply skills to exams, homework, and tests No guesswork. Just clear progress. 📚 Subjects I Teach Pre-Algebra • Algebra • Geometry • Trigonometry Pre-Calculus • Calculus • Functions • College Math 🎓 Exam Preparation IB • GCSE • A-Level • SAT • ACT • PSAT • SSAT • GRE 💡 Why Students Choose Me ✔ MSc in Applied Mathematics ✔ 14+ years of experience ✔ 1,500+ students taught worldwide ✔ ADHD-friendly, results-driven approach ✔ Clear explanations that actually make sense ✔ Focus on understanding—not memorization 🧪 What Happens in Your First Lesson • Identify the exact problems holding you back • Solve key questions step-by-step • Build a clear, personalized improvement plan You’ll leave the first session already understanding more than before. ⚠️ Limited Availability I work with a small number of students to ensure fast, focused results. 👉 Ready to Improve Your Math—Fast?

We couldn’t be happier with Kelvin. If I could I would give him 6 stars! He has great knowledge of a wide range of math topics. Most importantly he makes math fun. Our son says his positive energy is infectious; he now looks forward to his classes…even during the summer holidays. He’s done a fantastic job getting our son ready for the 9th grade. We will definitely use him during the school year to continue to give him a boost.
