The Science
Backed by over a century of memory science.
By 24 hours, up to 70% is gone. Without a system to fight this, most learning is wasted.
How we bend the curve
Short, focused 20-minute sessions prevent cognitive overload and let you learn in the flow of your day — no dedicated study block needed, and no half-remembered hour-long lectures.
Reviewing at gradually increasing intervals forces your brain to reconstruct the memory each time, making it progressively more durable. A 2006 meta-analysis of 254 studies confirmed distributed practice consistently outperforms massed practice across all learning contexts.

Actively retrieving information through quizzes and flashcards — rather than re-reading — triggers deeper processing and strengthens neural pathways. Roediger & Karpicke (2006) showed test-enhanced learning improved week-later retention by up to 50% vs. restudying.

The Method
A closed loop that keeps knowledge fresh — not just acquired
Build → Revise → repeat. Knowledge compounds over time.
The Curriculum
170+ bite-sized data science topics, organised into a structured path you can follow phase by phase.
Python, math, statistics and probability that every data role is built on.
Wrangling, analysis and visualization with the everyday Python stack.
Supervised and unsupervised models, plus how to evaluate them properly.
Deep learning and the architectures behind modern AI.
LLMs, embeddings and the techniques powering today’s AI products.
Deploying, monitoring and scaling models in real-world data systems.
Every topic uses the same Build → Revise loop, so what you learn actually sticks.
