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…
-
Today I spent my study session revising trigonometry, and it turned into a solid mix of recalling key identities, applying angle relationships, and solving problems that required careful reasoning rather than quick memorization. Even though I’ve learned these ideas before, revisiting them with more experience made everything connect more smoothly. I revised the sine rule…
-
Today I continued my work on differentiation, building on everything I’ve studied so far while sharpening my understanding through deeper revision. Even though I already know the basic rules, this session pushed me to apply them more fluently and to connect different ideas together in a more advanced way. I started by reviewing the fundamental…
