What this covers
Electron is part of the Electronics chapter. We teach it the way it is tested: the concept in plain English, then a worked example, then a question the student tries while the teacher checks the method.
How it is examined
It can appear in Paper 1 (objective) and Paper 2 (structured), and where an experiment applies, in Paper 3. We do not predict which questions appear; we prepare the technique for all of them.
A common mistake
How to study it
Learn the definition precisely, practise one or two SPM-style questions with full working, and link it to the rest of Electronics. If it keeps costing marks, a one-to-one lesson fixes exactly that.

What you need to know
Electron (standard 5.1) is part of Electronics in Form 5. Be able to define its key terms with the correct SI units and explain the idea in one precise sentence.
How it is examined
In Paper 1 this appears as an objective question; in Paper 2 as a define, explain, describe or calculate item. Watch the command word: "define" wants one sentence, "explain" wants the physics reason, "calculate" wants formula, substitution with units, and the answer with its unit.
We never predict which questions will appear.
