However, many top-tier JCs (like RI, HCI, NYJC, and VJ) have started integrating (Waves) and even basic Electric Fields into their promo papers to simulate the rigor of the actual A-Level Paper 2 and 3.
Always check your significant figures (SF). A common rule: follow the least number of SF given in the raw data. 4. Practice Strategy Timed Trials: jc1 h2 physics promo papers
O-Levels gave you Celsius. H2 Promos gives you the "Jolly Thermometer" or "Resistance thermometer." You’ll spend 15 minutes trying to linearize the graph. The hack: Always derive the linear formula first: $(X - X_0)/(X_100 - X_0) = (T - 0)/100$. Plug and chug after you write that line. Marks are given for the formula, not just the number. However, many top-tier JCs (like RI, HCI, NYJC,
Not the calculation—the explanation . They will show you a potentiometer or a Wheatstone Bridge circuit. They won't ask for the answer. They'll ask: "Explain why the galvanometer reading is zero." If you write "because no current flows," you get 0 marks. You must say: "The potential difference between points X and Y is equal, hence potential difference across galvanometer is zero." Precision is everything. The hack: Always derive the linear formula first:
