Statistical Inference vs Calculus Path

Statistical Inference is an independent study app built for students, self-learners, analysts, and anyone reviewing core inference ideas through focused practice. Work through 160 questions across Fundamentals, Practical Skills, Common Pitfalls, and Advanced Concepts. Each question includes an explanation so you can understand why an answer works, not just whether you got it right. Features: - FSRS spaced-repetition intervals to help reviews land at the right time - Weak-point heatmap to show where you need more practice - Daily challenge for consistent study - Mock exams for timed review - Offline practice for commutes, classrooms, and low-signal moments - No login required Use it to review estimation, confidence intervals, hypothesis testing, p-values, sampling distributions, power, errors, likelihood ideas, and common interpretation traps. Practice offline, no login required. Independent study app for Statistical Inference practice.

Build genuine differentiation fluency through short, focused practice sessions. Calculus Path turns derivative practice into a clear learning journey. Progress through 22 structured lessons covering core derivative rules, combined techniques, advanced methods and applications. Every session helps you practise efficiently, understand your mistakes and decide what to work on next. KEY FEATURES • Progress through multiple carefully structured differentiation lessons • Practise with fresh question variations • Receive immediate feedback after every answer • Discover the misconception behind each mistake • Strengthen weak skills with targeted repair questions • Unlock new lessons by demonstrating mastery • Build XP and maintain a daily learning streak • Revisit difficult concepts through a focused review queue • Keep your learning progress stored on your device • Set optional daily practice reminders • Continue practising without an internet connection TOPICS INCLUDE • Constant, power, exponential and logarithmic derivatives • Trigonometric differentiation • Product, quotient and chain rules • Implicit differentiation • Tangents, normals and stationary points Calculus Path is designed for secondary-school, pre-university and introductory university students who want more than an answer calculator. Instead of simply showing an answer, it helps you recognise methods, diagnose mistakes and develop lasting calculus skills. Start your path and make differentiation practice part of your day! Future versions/updates with other calculus skills will be developed.
