Cardiology boards prep, built around reasoning.

Each session: a written explanation, four to five retrieval questions with confidence ratings, a multi-step branching case, and a spaced-review queue tuned to how confident you were.

Four modes of practice in every session

Each session takes about 30 minutes and moves through reading, retrieval, a branching case, and spaced review.

Structured reading

Each session opens with a written explanation: mechanism first, then guidelines, then nuance.

Tiered retrieval

Four to five questions per topic, climbing from feature identification to mechanism. You rate your confidence before each answer.

Branching cases

Multi-step clinical scenarios. Wrong choices continue the case so you see how each decision plays out.

Confidence-aware spaced review

A modified SM-2 scheduler that uses correctness and confidence together. Items you got wrong with high confidence come back soon; items you got right with low confidence stay in rotation.

Written from the guidelines and the trials behind them.

Sessions draw from the ACC/AHA and ESC guidelines and the landmark trials they cite. Each topic is reorganized into the five-section session format: reading, tiered retrieval, branching case, spaced-review facts, and session close.

Confidence is part of the data.

Before you see the answer to a question, you rate your confidence: low, medium, or high. After every fact review, you self-grade on the same three buckets.

Those ratings feed a modified SM-2 scheduler:

Right with high confidence: the fact moves further out.
Wrong with high confidence: it comes back soon.
Right with low confidence: it stays in rotation.

Every review is stored with its confidence, time, and grade. That history shapes your dashboard, your daily plan, and the queue you see tomorrow.
