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…

Today’s physics revision was all about radiation, but instead of treating it as a basic review, I focused on truly understanding the behaviour, patterns, and reasoning behind every concept. Radiation is a major part of IGCSE physics, and revisiting it with a sharper mindset made everything feel clearer and more connected. I began with the…

Today’s chemistry study session was a full revision of metals, but instead of treating it as a simple recap, I approached it with deeper understanding and more advanced reasoning. Metals are one of the most important topics in IGCSE chemistry, and going through everything again helped me see how all the ideas connect. I began…

Today’s physics lesson was all about graphs, but not the basic “read the value from the axis” type. We studied the deeper, more advanced side of interpreting graphs in physics — the kind that appears in electricity, pressure, heat, and motion. What made this session challenging wasn’t the content itself, but the level of analysis…

Today’s physics revision focused on plane mirrors, but not in the simple way we learned before. This session pushed everything into advanced geometric reasoning, where every reflection became a precise angle problem rather than just a quick sketch. It felt like a mixture of physics and high-level geometry combined into one challenge. We began by…

Today’s physics lesson took me deep into one of the most mind-bending topics yet — electromagnetism. It’s strange how something completely invisible can be so perfectly predictable through mathematics. We began with the basics of magnetic fields, revisiting how current-carrying wires create circular field lines, and how solenoids act like controllable magnets. But soon, we…

Today’s math session was all about advanced differentiation — not just finding derivatives, but truly understanding how to use them. It felt less like mechanical computation and more like decoding the behavior of functions. We began with a quick revision of basic differentiation rules — product, quotient, and chain rules — just to warm up.…

Today’s math class took trigonometry to a whole new level — the advanced world of compound angles, where we learned how to work with expressions like sin(a + b), cos(a + b), and tan(a + b). It wasn’t just about memorizing formulas — it was about understanding why they work and how they’re used to…

Today’s math lesson was all about one of the more elegant and lesser-known theorems in geometry — Menelaus’ Theorem. It’s not as famous as Pythagoras or Thales, but it’s a powerful tool for solving problems involving ratios in triangles and transversals. And honestly, it felt like uncovering a hidden trick that makes complicated geometry suddenly…
