AP Prep (CS/Calculus/Pre-Calc/Physics/Chem): Certified C++ Tutor with 5 Years – USACO & Basics

I'm Abdulrahman, a Computer & Information Engineering graduate from Zewail University for Science & Technology, one of Egypt's top STEM institutions. I have hands-on teaching experience as a Junior Teaching Assistant for Object-Oriented Programming (OOP) using C++, where I guided students through projects, lab assignments, and problem-solving sessions. My tutoring covers a wide range of subjects: Mathematics (Pre-Algebra, Algebra I & II, Pre-Calculus, Calculus I/II/III, Linear Algebra, Statistics, Trigonometry, Differential Equations), Computer Science (Java, C++, Python, OOP, Data Structures & Algorithms, SQL, Databases), AP exams (AP Calculus AB/BC, AP CSA), IGCSE Math & CS, USACO competition preparation, Machine Learning, Deep Learning, Computer Vision, Signals & Systems, Digital Signal Processing, Control Systems, and Digital Design. My teaching philosophy is simple: logic before syntax, understanding before memorization. I never let a student open a compiler until the concept makes sense on paper first. I use visual tools, real examples, and live coding to make abstract topics click. I've successfully tutored students from the US, Singapore, Turkey, Canada, UAE, and the UK — from Grade 10 algebra all the way to Master's-level Computer Vision. My trial-to-subscription rate on Preply is 83%, and I maintain a 100% reply rate within 24 hours. Every session includes follow-up homework, practice problems, and lab exercises. First lesson is always free.
