Supported Exam Types

Example Conversation

Scenario: Student has AP Chemistry exam in 3 weeks

Student: I have my AP Chemistry exam on May 15th. I'm currently at an intermediate level. Can you set me up?

Claude: I'll set up your AP Chemistry exam prep right away!

[calls set_exam with profileId="student", examType="AP_Chemistry", examDate="2025-05-15", currentLevel="intermediate"]

Great! I've configured your AP Chemistry prep:

• 21 days until your exam
• 10 topics identified: Atomic Structure, Chemical Bonding, Stoichiometry, Gas Laws, Thermodynamics, Chemical Equilibrium, Acids and Bases, Electrochemistry, Kinetics, Nuclear Chemistry
• 48 practice cards seeded into your study queue
• Weekly goal: Master 3-4 topics per week

Student: What should I study today?

Claude: [calls get_daily_session]

Today's session (12 questions, ~30 min):

Focus areas: Stoichiometry, Gas Laws, Acids and Bases

1. [Stoichiometry] How many grams of H₂O are produced when 4.0g of H₂ reacts completely with excess O₂?
2. [Gas Laws] A gas occupies 2.0 L at 300K and 1.0 atm. What volume at 600K and 2.0 atm? ...

Student: For question 1, I think it's 36 grams.

Claude: [calls answer_question with answer="36 g"]

Correct! Well done.

36 g is right. 2H₂ + O₂ → 2H₂O. Moles H₂ = 4.0g / 2.0g/mol = 2.0 mol. From stoichiometry, 2.0 mol H₂O × 18 g/mol = 36 g.

Next review: in 3 days

Student: Let's do a mock exam!

Claude: [calls start_mock_exam]

Starting your AP Chemistry mock exam:

• 60 questions
• 190 minutes time limit
• Answer all questions, then use submit_mock_exam when done.

Student: How ready am I overall?

Claude: [calls get_readiness]

Readiness Score: 67/100

• Estimated AP Score: 4/5 (Well Qualified)
• Topics mastered: Chemical Bonding, Atomic Structure
• Weak areas: Electrochemistry (40%), Thermodynamics (50%)
• Trend: Improving
• 21 days remaining — excellent time to close the gaps!

Recommendation: Focus on Electrochemistry and Thermodynamics this week. You're on track for a 4!

How FSRS Works

FSRS-5 (Free Spaced Repetition Scheduler) is a state-of-the-art algorithm that models human memory:

• Stability (S): How long you'll remember something (in days)
• Difficulty (D): How hard the material is for you (1-10 scale)
• Retrievability (R): Probability you can recall it right now (0-1)

After each answer, the algorithm calculates your next optimal review date. Cards you find easy get longer intervals; cards you struggle with come back sooner. This minimizes total study time while maximizing retention.
