Get test help without leaving your practice screen
You're working through a practice test — SAT math, GRE verbal, MCAT biology, bar exam questions. You get a question wrong and don't understand why. You read the answer explanation but it's too brief. You need someone to walk through the reasoning. Normally you'd search for a video explanation of that specific question type, hope it applies, and try to map it back to your test.
Lumini sees your test screen. Hold Ctrl+Option, point at the question, and ask: "Why is C the correct answer and not B?" Lumini sees the question, the answer choices, and — if visible — the explanation. It walks through the logic, pointing at key phrases in the passage or steps in the calculation.
How Lumini helps with different test types
**Reading comprehension:** "I narrowed it down to A and D — why is D better?" Lumini sees the passage and the answer choices, and explains the evidence in the text that supports D and rules out A. It points at the relevant lines.
**Math and quantitative:** "How do I solve this without a calculator?" Lumini sees the problem and works through the mental math, estimation strategies, and shortcuts that save time on test day.
**Science and data interpretation:** "What is this graph showing?" Lumini sees the figure, the axes, the data points, and explains the trend in plain English. It helps you interpret the experiment described.
**Vocabulary in context:** "I don't know what 'perfunctory' means in this sentence." Lumini sees the word in the passage and explains not just the definition but how to infer meaning from context — a key test-taking skill.
