1.1What is an emotion?
Emotions are experiences that occur when we regard our situation as relevant to our active personal goals. It is a mental state caused by stimuli, characterised by three kinds of change:
- Our behaviour, how we act.
- Our subjective experience, how we feel.
- Our physiology, how the systems of the body function.
The most prominent behaviours are facial expressions. Their perception is comparable across cultures; their expression is not, because of display rules.
1.2Emotion versus mood, and arousal
- Emotion
- Short-lived, with a clear target.
- Mood
- Long-lasting, with no target.
- Arousal
- The state of being activated, such as a raised heart rate or sweating.
Short rounds of questions, picked from what you still need to learn.
The real exam, before the real exam. Same length, same clock, same grading.
Read it like paper. Use it like software.
The lecture summary is a booklet of A4 sheets on a lit desk. Highlight a passage and the note sits beside it. Point at a term and the definition opens. Zoom in and the page grows around your cursor.

Practice that knows what you still need.
Every question asks one extra thing: were you sure? A confident wrong answer becomes a priority. A lucky right answer comes back once more. The queue reorders itself from those two signals.
- "I don't know" is an answer. Abstaining is recorded as a measurement of you, not of the question, so the item's own difficulty stays honest.
- Feedback names the lecture. Every explanation says which lecture it came from, one click from the page in the reader.
- Wrong answers become a queue. Home shows them as "Worth clearing first" with the gold mark that means "assembled from your own answers".
- A run says what it is before it starts. How many questions, how long, and how last time went, before the first question is dealt.
The ten labels. A question carries several and exactly one leads. They say what you have to do, not what the question is about.
It learns how you learn.
Every answer lands on one cell: the lecture it came from and the label it carried. The map fills in as you work, and the next session is drawn from the palest cells.
Two axes, one cell
Lecture times label. A wrong answer dings every label the question carries; the leading label is what your results page is partitioned on.
Difficulty is measured, never authored
A question nobody has answered reads exactly neutral. The estimate is shrunk toward neutral until the evidence supports a stronger claim, and your own answer never inflates your own mastery move.
A bad question retires itself
Nightly stats compute each item's discrimination. One that the strong students get wrong and the weak get right is shadowed, silently, and never drawn again until a person has looked at it.
Focus, Normal, Skip
A lever on every lecture. Focus weights the draw at 1.6, Normal at 1, Skip at 0 and takes the lecture out of readiness. The syllabus order never changes.
Diagnostic, Smart Session, the review queue, the mastery map and the confidence toggle.
Full control, every Personalized feature switched off. Still recorded, just not steered. Switch any time in Settings.
Nothing is marked or revealed until you submit. Your answers save as you go, so a dropped connection does not cost you the paper.
Hand in the paper?
7 of 8 answered, 1 marked for review. The clock has 11 minutes left. You cannot change answers after this.
6 of 8 correct. The cesuur for this paper anchors 55% at a 5.5, the same curve the faculty applies to the real exam.
C = 0.55 × 8 = 4.4 · s = 6 · M = 8 → 7.5
The real exam, before the real exam.
A mock exam is a sitting. The paper is modelled on the faculty's own: the same number of questions, the same time, nothing revealed until you hand in.
- The clock hands it in for you. When it reaches zero the paper is submitted with whatever you answered by then, exactly like the room.
- Graded on the cesuur. The pass mark anchors at 5.5, guess correction included where the faculty applies it. The number you see is the number you would have got.
- Results by label. Two out of two on definitions and zero on negatively worded questions is a different afternoon of work than “75%”.
- Scored on what you sat. If an author corrects a question tomorrow, your paper is still marked against the key that was on screen today.
See yourself getting ready.
A streak that survives a Tuesday off. A weekly goal in hours, measured against the hours you actually put in. Mastery by course, with the readiness ring on the course page climbing since week one.
- Compared only to you. Study time this week beside your own goal, never beside a leaderboard.
- One graded answer starts a day. Reading does not count as a streak day. Answering does.
- Written as progress. The interface has no "weak", no "behind", no "gaps". The words it uses are below.
