Students taking a first philosophy paper who want something to test themselves against between lectures, candidates preparing for entrance examinations with a philosophy or critical-reasoning component, and readers who have picked up the ideas from books and conversation and want the actual arguments underneath. No prior study is assumed; the course opens with how philosophical reasoning works before applying it anywhere.

Two gaps recur. The first belongs to the student who can name the positions — dualism, compatibilism, utilitarianism — and stalls when handed a case and asked which position it supports, because naming was never what the exam tested. The second belongs to the confident reader who holds strong views on free will or morality and has never been asked to state the best objection to their own position. Both close the same way, by being asked instead of told.

One question at a time, with an explanation shown on every answer rather than only the wrong ones. Nothing to install and no lectures to sit through. The AI guide tracks which labels you keep missing and steers later questions toward those gaps, so your time goes into what has not landed rather than what you already answer on reflex. Progress is stored per label, so a ten-question session is still a useful session.

The explanations carry the reasoning, not just the verdict. On an argument-form question the premises are laid out and the inference checked step by step, so you can see whether the conclusion actually follows. On an ethics question the competing theories are applied to the same case, which is the difference between reciting utilitarianism and being able to say what it recommends here.

A large share of exam marks and public confusion turn on the same handful of distinctions. This course tests each one directly:

• Validity concerns form; soundness additionally requires the premises to be true
• A necessary condition and a sufficient condition are not interchangeable
• Justified true belief is not obviously enough for knowledge, as Gettier showed
• Determinism and free will are incompatible only if you reject compatibilism
• Rule utilitarianism can forbid what act utilitarianism permits
• The problem of evil targets a specific conception of God, not belief in general
• Asking after the meaning of life differs from asking after meaning in a life
• A descriptive claim never entails a normative one without further premises

Coursera and edX host free university introductions to philosophy, and open courseware from major departments is genuinely excellent for meeting the material the first time. Udemy offers structured video courses at your own pace. This course does a narrower job than any of them. It assumes the arguments have already reached you and tests whether you can apply them to a case you have not seen, which is what an examiner is actually checking. Watching a lecture on the trolley problem and being able to say what the doctrine of double effect implies about a variant are different achievements.

Retrieval beats recognition. Reading a chapter on Kant feels productive because the argument is persuasive while you are reading it, but following an argument is not the same as being able to reconstruct it, and reconstruction is what you are marked on. Answering before the explanation appears forces that reconstruction, and the questions you get wrong are the only honest map of what you do not yet understand. Work in curriculum order, because the dependencies are real: you cannot assess the problem of evil without knowing what makes an argument valid, and metaethics assumes you already have the normative theories. If you want to sharpen argument evaluation specifically, Logical Reasoning drills inference and assumption-spotting in depth.
