The DSE loves "Explain" questions. For example: "Why does the bulb get brighter when you add a resistor in parallel?" A poor answer: "Because the resistance goes down." (Too vague) An excellent answer (found in top mock marking schemes): "Adding a resistor in parallel decreases total circuit resistance. By V=IR with constant voltage source, total current increases. The bulb experiences the same voltage but higher current, so P=I^2R increases, hence brightness increases." Practice writing full sentences, not just equations.
