Yeriko - Know your tutor

Hello — I’m Yeriko. I teach mathematics in a way that actually makes sense. No memorizing random steps, no confusion — just clear logic, patterns, and structure so you understand why things work. I taught precalculus at Oakland University for 2 years, and for the past 5+ years I’ve been working with students online, helping them improve their grades, pass exams, and build real confidence in math. My focus areas: Precalculus Algebra Trigonometry Whether you’re stuck on assignments, preparing for a big exam, or feel like you’ve fallen behind, I’ll help you break everything down step-by-step until it clicks. In our sessions, you’ll learn how to: Approach problems with a clear strategy Recognize patterns instead of guessing Avoid common mistakes that cost points Build confidence solving problems on your own I specialize in working with students who feel overwhelmed or lost — and turning that into clarity fast. We’ll go at your pace, simplify complex topics, and focus on what actually matters for your class. I also help with: Homework & assignments Quiz, midterm, and final exam prep Relearning foundational topics Last-minute review sessions No fluff, no overcomplication — just math explained in a way that sticks.
