I’m Oscar, and I tutor AP Calculus with a focus on both AB and BC levels. My background in applied mathematics and three years of tutoring experience have allowed me to help students consistently score 4s and 5s. I specialise in preparing students for the exam by breaking down complex calculus into simpler, actionable steps.

I’m a biology graduate with a focus on molecular and cellular systems, specialising in AP Biology tutoring. I provide tailored support in genetics, physiology, and ecology, helping students excel in exams and lab-based coursework. With experience in both classroom and one-on-one settings, I aim to build strong scientific foundations and academic confidence in every student.

Backed by five years of teaching experience, I guide students across the U.S., Singapore, and Europe through the AP Economics curriculum with a focus on both Micro and Macro. From helping build foundational theory to sharpening exam strategies, my students consistently achieve top results by learning how to think like economists, not just memorise content.

With a background in data science, I help students navigate the core concepts of AP Statistics—covering probability, distributions, regression, and inference. I’ve worked with students in the U.S., Middle East, and Europe, offering structured support for coursework, exam readiness, and extended assignments. My goal is to build strong statistical thinking that lasts beyond the test.

My work in theoretical physics helps me guide students through AP Physics with confidence—from mechanics and electricity to motion and energy systems. I’ve helped learners grasp both the problem-solving and conceptual aspects of the course, preparing them for top scores on the AP exam through focused and structured support.

With a doctorate in chemical sciences and a passion for guiding students through AP Chemistry, I support learners in mastering everything from atomic structure to thermodynamics. My work bridges academic theory with exam precision, helping students develop the skills they need to excel in the AP exam and deepen their understanding of chemistry.

I teach AP History with a focus on developing strong analytical skills, essay writing techniques, and a clear understanding of historical themes and timelines. With a background in History and experience guiding students through DBQs, LEQs, and multiple-choice strategies, I help them approach the AP curriculum with confidence. My sessions cover U.S. and World History topics, supporting students as they make connections across time periods and learn to interpret sources critically. 

As a tutor with a background in computer engineering, I teach AP Computer Science with a strong focus on Java, data structures, and logical reasoning. I’ve worked with students on mastering key exam topics while building real-world coding proficiency. My sessions are structured to develop confidence in problem-solving and prepare students for top scores on the AP exam.
