In my computer science lesson, I focused on revising input and output devices, which are essential for how a computer communicates with the outside world. Even though this topic is familiar, revisiting it helped me understand more clearly how hardware and users interact through data flow. We started with input devices, which allow users to…

In my computer science lesson, I focused on revising the internal components of a computer, especially the CPU and what actually happens inside it. Instead of just naming parts, this revision helped me understand how each component works together to make a computer function smoothly. The main focus was the Central Processing Unit (CPU), which…

My physics lesson yesterday was a full revision session on electricity, covering almost everything from the basics to the deeper reasoning behind each concept. Even though it was a revision, the class was packed with details — the kind that really test whether you understand electricity or you only memorized formulas. We went through current,…

My physics lesson today went even further into the world of lenses, pushing past the basic ray diagrams and into the full mathematical framework behind how images form. Instead of just drawing the principal rays, we focused on the core formulas, how to apply them correctly, and how to handle tricky problem variations that appear…

My geometry lesson today focused on two powerful tools that appear constantly in Olympiad-level problems: Ceva’s Theorem and the Angle Bisector Theorem. Even though both theorems look clean and simple at first, applying them correctly requires a strong understanding of ratios, triangle structures, and how lines interact inside a triangle. We started with the Angle…

My physics lesson yesterday was all about revisiting the topic of energy, and even though it wasn’t one of the super-advanced sessions, it was still a really important one. Energy is one of those core ideas that keeps showing up everywhere in physics—mechanics, electricity, heat, waves—so getting the fundamentals perfectly clear actually makes the harder…

Today’s physics lesson was all about prisms, and even though prisms seem simple at first glance, the deeper we went, the more the geometry began to bite. This wasn’t just “light enters, bends, and comes out”—it was a full exploration of how refraction interacts with the geometry of a transparent solid, and how every angle…

Today’s physics lesson was all about lenses — not just the theory, but the actual skill of drawing accurate ray diagrams. Even though I’ve learned about lenses before, this session pushed me to be much more precise and systematic with every construction. We started by revisiting the two main types of lenses: convex (converging) and…

Today’s chemistry lesson was all about revisiting organic chemistry, and honestly, it felt like tightening every bolt in the entire topic. Even though I’ve studied organic chemistry before, going back through the details helped everything click into place much more clearly. We started by reviewing the basics: hydrocarbons, homologous series, and the structure of alkanes,…

Today’s computer science lesson was all about going deeper into how computers actually handle numbers. Instead of just writing values in decimal, we focused on binary — and more specifically, how computers perform addition, subtraction, and negative number representation using 2’s complement. Even though I’ve used binary before, this lesson finally connected all the pieces…
