About

Hi! I’m a high school student who is passionate about math and computer science. I enjoy problem-solving, coding, and exploring how algorithms can be applied to real-world challenges. I’m joining Schoolhouse to share my knowledge, help other students build confidence in these subjects, and learn from the global community along the way. My goal is to make math and computer science more approachable and enjoyable for everyone.

Upcoming Sessions

C++ from Zero: No Experience Needed

    6th session

This session covers C++ basics from the ground up, including variables, conditions, loops, and simple problem-solving. Learners will actively participate by writing small pieces of code together and asking questions through chat at any time. No prior experience is required. For learner convenience, this series is offered in repeated time slots. Sessions are grouped into identical-content pairs (e.g., Sessions 1 & 2, Sessions 3 & 4), and this pairing pattern continues throughout the series. Learners only need to attend one session per pair.
