Read the guide →Earth, weather & environment
IntermediateA stone records processes, but its appearance alone does not reveal a complete history.
Learning outcome: Classify formation processes, reconstruct a sequence, calculate an idealised half-life age and recognise what a geological date actually measures.
Read the guide →Mathematics
AdvancedDifferent random samples produce different estimates even when the population is unchanged.
Learning outcome: Distinguish standard deviation from standard error, calculate mean and proportion intervals, interpret confidence correctly, and identify uncertainty that the formulas omit.
Read the guide →Indian biographies
BeginnerA poet can shape how people imagine a place; an organiser can help people act together.
Learning outcome: Explain how poetic voice works, assess a public claim, and connect literary and political milestones without assuming that one automatically caused the other.

Learning outcome: Explain how exclusion can survive an open-door policy, distinguish educational access from learning, and use evidence to assess a reformer’s contribution without reducing a movement to one person.
Read the guide →Science & evidence
BeginnerWhy does a fair test matter? Learn how variables, repeated measurements and alternative explanations turn a sensible guess into a conclusion you can defend.
Learning outcome: You will turn a broad curiosity into a testable question, plan a fair comparison, and distinguish a result from the explanation offered for it.
Read the guide →Mathematics
IntermediateAdding a fixed amount and multiplying by a fixed factor produce very different patterns.
Learning outcome: Build recursive and explicit rules, sum finite sequences, compare linear and compound change, and check the assumptions behind a projection.
Read the guide →Research & achievements
BeginnerA chip announcement becomes more meaningful when we understand the chain behind it: instructions, logic, fabrication, a circuit board and a successful start.
Learning outcome: Distinguish an instruction set from a chip, trace a simple control program, calculate execution time and energy, and propose tests beyond a successful boot.
Read the guide →Older people
BeginnerMeaningful company grows from being known, heard and able to contribute.
Learning outcome: You can plan a small intergenerational activity, adapt contact to an individual preference and judge participation without making medical claims or labelling someone lonely.

BeginnerSoil is a developing system of minerals, organic matter, organisms, air and water.
Learning outcome: Read a soil profile, separate texture from structure, calculate equivalent soil loss and design a fair comparison of protective cover.
Read the guide →Physics
IntermediateA student can walk a long route and finish near the starting point.
Learning outcome: Calculate journey averages, interpret position–time and velocity–time graphs, and solve constant-acceleration problems while checking when their assumptions apply.
Read the guide →Digital skills
BeginnerScams often persuade people to perform an ordinary action for a false reason: sign in, approve a payment or install an app.
Learning outcome: Recognise common persuasion tactics, explain two worked scams, distinguish receiving money from authorising a debit, and prepare a factual incident record.

Read the guide →Indian biographies
IntermediateRamanujan found remarkable relationships among numbers.
Learning outcome: Calculate small partition numbers, explain one Ramanujan congruence in words, and distinguish examples, counterexamples and proof.
Read the guide →Research & achievements
IntermediateCan excavated soil become part of a useful building material while carbon dioxide becomes a solid mineral? IISc research published in 2024 lets us study this question through three linked tests: chemical change, engineering performance and environmental accounting.
Learning outcome: Explain a carbonation reaction, calculate compressive strength and a simplified carbon balance, and distinguish early strength gains from long-term or whole-life claims.
Read the guide →Philosophy & reasoning
IntermediateDoes being aware of a changing thought make awareness itself another changing thing? Classical Sāṃkhya develops a distinctive answer.
Learning outcome: Explain puruṣa and prakṛti, trace the twenty-five principles, and apply the distinctions between mental activity, identification and witnessing to a worked example.
