How Our Algorithm Helps You
Work Smarter
While most study apps don't even keep track of your progress, FourtyFive takes it a massive step further. We power your dashboard with the most detailed, scientifically rigorous algorithms available to accurately reflect your true abilities and give you a precise report of your exact standing in the IB.
The Six Pillars of True Mastery
To give you a Mastery Score you can actually trust, the FourtyFive engine evaluates every single question you answer through six distinct lenses of cognitive science.
Proven Capability
We don't treat all answers equally. Our engine prioritizes your recent breakthroughs while requiring consistent evidence of success. An old mistake won't permanently drag you down once you've proven you understand the concept.
Exam Fluency
The IB is a race against the clock. We track your "Marks Per Minute." Taking 20 minutes to solve an easy 5-mark question isn't mastery. We ensure your speed aligns with actual exam conditions.
Memory Retention
The IB is a 2-year marathon; forgetting is natural. Using Spaced Repetition science, our algorithm calculates your dynamic "memory half-life" and predicts exactly what you've forgotten over time.
Statistical Confidence
Guessing correctly once does not equal 100% mastery. Our engine requires a healthy volume of practice. We build statistical confidence in your score only as you build a proven track record.
Self-Awareness
Knowing what you don't know is a critical study skill. We factor in your subjective self-ratings, blending your personal confidence levels with hard, objective data.
Real-Time Adaptability
Suddenly acing a topic you used to struggle with? Or slipping up on an old favorite? The engine instantly registers these shifts, adapting your Mastery Score in real-time so your dashboard is never out of date.
Beyond Basic Averages
| The Student Scenario | Standard Study Apps | The FourtyFive Engine |
|---|---|---|
| The "Lucky Guess" You answer just 1 question and get it 100% correct. |
Awards you "100% Mastery" immediately. | Recognizes a small sample size. Protects your score from artificial inflation until you prove consistency. |
| The "Slow Thinker" You get the right answer, but it takes triple the standard exam time. |
Marks it simply as "Correct". | Adjusts your Fluency score. Warns you that while your accuracy is great, your exam pacing needs work. |
| The "Long Term Fade" You scored 95% on a topic in Year 1, but haven't reviewed it in 6 months. |
Your dashboard still says you have a 95% average. | Applies memory decay. Your score safely lowers, gently signaling that it's time for a revision session. |
Trust the Process. Trust Your Score.
For students, FourtyFive eliminates the anxiety of wondering "Am I actually ready for this paper?" For parents, it provides unparalleled visibility into genuine academic progress.

The result?
You study less – while learning more
