This is the reading directory for the How to Perform in PSLE | Learner’s Guide series. It brings the original eduKateSengkang foundation volumes together with the continued guides published on eduKateSG. Choose the subject or skill that matches your question, read the worked reasoning, try an unfamiliar example, and return later to see whether you can solve it without a hint. There are 333 published guides in this directory, covering numbered volumes 0001–0307.
Every link below opens an existing published guide. Some early volumes have two different articles with the same volume number. They cover different learner jobs, so both are included. This is a guide to the actual articles, not a replacement for their detailed teaching. Pick one problem you need to solve rather than attempting to read the whole directory in one sitting.

- English — comprehension, vocabulary, grammar and writing (83 guides)
- Mathematics — representations, problem solving and checking (83 guides)
- Science — evidence, experiments, explanations and mechanisms (82 guides)
- Across subjects — exam technique, transfer and independent learning (85 guides)
For an overview of PSLE learning across subjects, see the existing PSLE Learning Guide. For deeper teaching of individual topics, use English Learning Hub, Mathematics Learning Hub or Science Learning Hub. Those hubs keep the bigger subject picture; this index focuses on practical examination-performance jobs.
How to use one guide
Start with the action that is failing: identifying a requirement, choosing a method, retrieving a concept, connecting two steps, explaining evidence, or checking an answer. Read only the guide that addresses that job. Cover the worked answer before trying the example yourself. If your answer differs, identify the earliest mistaken step and repair it. Use a different question later—preferably in another session—to test whether you can transfer the skill without copying the example.
English, Mathematics and Science have different answer forms. An English answer may need a precise inference grounded in a phrase. Mathematics may need a labelled quantity, calculation and sensible unit. Science may need an observation, relationship or mechanism with the right degree of certainty. The cross-subject guides help you decide how to work under examination conditions, but they do not replace detailed syllabus teaching.
