Step 2 - Adaptive Learning Engine (Weeks 9-16): Add diagnostic testing and personalized study plans. When a student signs up, they take a 20-question adaptive diagnostic that identifies weak areas (algebra, geometry, data analysis, etc.). The AI generates a custom 8-week study plan prioritizing their gaps. Implement spaced repetition algorithms (similar to Anki) so questions resurface at optimal intervals. Add progress dashboards showing score predictions and improvement trends. Launch paid tier at $29/month for unlimited questions and personalized plans. Goal: Convert 10% of free users to paid (50 paying customers), achieve $1,500 MRR, validate that personalized plans improve scores (A/B test against random question order).

Step 3 - Full-Stack Test Prep Platform (Weeks 17-32): Expand to all SAT sections (Reading, Writing, Math) and add essay grading using GPT-4 (compare student essays to high-scoring examples, provide specific feedback on thesis, evidence, and organization). Build a mobile app (React Native or Flutter) for on-the-go studying. Add gamification (streaks, leaderboards, achievement badges) to boost engagement. Integrate live coaching: students can book 30-minute video sessions with human coaches (hire 5 part-time coaches, pay $25/hour, charge students $49/session or include 2/month in $99 tier). Launch referral program (give 1 month free for each referral). Goal: 5,000 active users, 500 paying subscribers, $15K MRR, 30% month-over-month growth, NPS above 50.

Step 4 - Outcome Guarantee and Scale (Weeks 33-52): Implement outcome tracking by asking students to report their official SAT scores after taking the test. Offer a money-back guarantee: if a student completes 80% of their study plan and doesn't improve by 100+ points, refund their subscription. This requires building a prediction model (train on historical data to estimate score improvement based on study behavior). Launch intensive 3-month bootcamp at $299 with guaranteed results. Expand to IELTS (huge market in India, Southeast Asia, MENA) by licensing question banks and fine-tuning AI on IELTS-specific content. Build SEO moat: publish 500+ blog posts and YouTube videos solving past exam questions (target long-tail keywords like 'SAT Math Question 15 Section 3 Practice Test 8'). Goal: 20,000 active users, 2,000 paying subscribers, $60K MRR, 50% gross margins, raise $500K-1M seed round to expand to more exams and geographies.
