Physics has a reputation as one of the hardest school subjects — but most of the difficulty students experience comes from studying it the wrong way, not from the subject itself being unusually hard. Here's a concept-first approach that works across O Level, A Level, and entry-test preparation (MDCAT, ECAT).
Why Physics Feels Harder Than It Is
Physics is often studied like a memorization subject — memorize the formula, plug in numbers. This works for the easiest questions but breaks down the moment a question is phrased differently than the textbook example, because the student never understood why the formula works, only that it exists. Physics rewards conceptual understanding far more than most school subjects.
Start With the Concept, Not the Formula
Before memorizing a formula, make sure you can explain in plain language what it describes and why it makes physical sense. For example, before memorizing F = ma, understand what it actually means: a larger force is needed to accelerate a larger mass at the same rate, or the same force accelerates a smaller mass faster. This understanding lets you recognize when and how to apply the formula even in an unfamiliar question format — which is exactly what exam questions are designed to test.
Draw Diagrams — Every Time
Physics problems, especially in mechanics and electricity, become far clearer with a diagram: forces acting on an object, a circuit layout, a ray diagram for optics. Students who skip diagrams and try to solve problems purely algebraically make far more errors identifying what's actually being asked.
Practice Problems, Not Just Theory
Understanding a concept and being able to apply it under exam conditions are different skills. After learning a topic conceptually, immediately move to solving a mixed set of problems on it — not just the easiest textbook examples, but past-paper-style questions that require applying the concept in a less obvious way.
Build a Formula Sheet — Then Stop Relying On It
Creating your own formula sheet (rather than using a pre-made one) is itself a useful active-recall exercise. But the goal is to reach the point where you don't need to check it during timed practice — use it as a learning tool early on, then wean off it as exam day approaches.
Common Questions
Why do I understand Physics in class but struggle on exams? This usually means the understanding is passive (you can follow an explanation) rather than active (you can produce the solution yourself) — more independent problem-solving practice closes this gap.
How is Physics different for MDCAT/ECAT versus O Level/A Level? The underlying FSc-level content overlaps significantly, but MDCAT/ECAT demand much faster, MCQ-based problem-solving under strict time pressure, so practice should shift toward timed numerical MCQs as the exam approaches.
Should I memorize derivations? Understanding a derivation well enough to reconstruct it is usually more valuable than rote memorization, since it also deepens understanding of the underlying formula.
