Every quiz, flashcard and practice question becomes evidence. TurboStudy turns it into an Exam Readiness Score from 0 to 100 for each course, tells you how reliable that score is, and points you to the topics that need work. Topics you haven't practiced count against you, so the score stays honest.
Confidence shows how much evidence is behind the number. It grows as you answer more questions, cover more topics and use more than one way of studying.

Readiness 78 · Confidence: Low
You've only practiced 35% of exam topics.
What it means: the score looks good, but it's based on a small part of the course. Practice the remaining topics and the score — and its confidence — will tell you much more.
Step 1: Upload
Lectures, slides, PDFs and notes.
Step 2: Study
Notes and flashcards from your material.
Step 3: Test
Quizzes, recall and practice exams.
Step 4: Measure
Readiness by topic, with a confidence level.
Step 5: Improve
Study what moves your readiness most.
Readiness is an estimate based on your TurboStudy activity and uploaded material. It does not predict your actual grade.

Recovery Mode
PremiumWhen a topic keeps tripping you up, Recovery Mode walks you through it in four short steps instead of another round of re-reading.
Explain
A short, clear explanation of the idea you're missing, from your material.
Practice
A few targeted questions on just that idea.
Apply
Use it on a new scenario, the way an exam would ask.
Retest
Come back later to check it stuck.
AI Notes
TurboStudy turns slides, readings and transcripts into organized notes: key ideas by topic, definitions, examples and what your material emphasizes. Every section links back to the page or slide it came from.
How a firm's costs change with output, and why average cost is U-shaped.
Marginal cost (MC)
Slide 7The cost of making one more unit. When MC is below ATC, ATC falls.
Short run vs. long run
Slide 11Short run: at least one input is fixed. Long run: every input can change.
Economies of scale
Slide 18Long-run ATC falls as output grows, then rises with diseconomies of scale.
Flashcards
Cards are written from your own material, one idea per card. Spaced repetition schedules every review, so your time goes to the cards you're about to forget — not the ones you already know.

Quizzes
Multiple choice, true/false, fill-in-the-blank and short answer — with instant feedback and an explanation for every answer. Every result updates your topic mastery and your Exam Readiness.
In the long run, a perfectly competitive firm earns…
Correct. Entry and exit push price to minimum ATC, so economic profit is zero. (Lecture 6, slide 22)
AI Tutor
The tutor searches your lectures and readings, answers with citations, and labels anything that comes from general knowledge — so you always know where an answer came from.
The same idea applies to any average — like your grade average and your next test score.
Practice Exams
PremiumTimed, exam-style tests built from your course material, mixing topics and question types. Results feed your Exam Readiness and show which topics cost you marks.

When the tutor uses general knowledge instead of your material, it says so.
Always verify important information against your course material and your instructor.
Your Exam Readiness Score (0–100) is a weighted combination of the evidence from your practice in a course: quiz mastery, active recall, practice exams, flashcard mastery, how much of the course's topics you've covered, and how recently you've practiced. Recent answers and harder questions count more, and topics you haven't practiced pull the score down instead of being ignored.
A score appears once you have at least 5 graded answers. Every score comes with a confidence level — Low, Medium or High — based on how many questions you've answered, how many topics you've covered and how many different ways you've studied.
