How ClinicalStem works
The short version of what makes this more than a question dump — and how to get the most from it.
Tutor vs Timed practice
Tutor mode shows the answer and a full explanation after every question — the way to learn. Timed mode hides feedback until the end and runs a clock, so it feels like the real exam. Pick either from a topic's presets or the custom builder.
Spaced repetition
Every question you answer is scheduled by an SM-2-style algorithm: get it wrong and it comes back tomorrow; get it right and the gap grows. Your flashcards and question bank share one review queue, so "Due today" means the things you're about to forget — the highest-value minutes you can spend.
Readiness & the pass mark
Your readiness gauge estimates where you stand against the 70% OPRA pass mark — overall and per domain. Green means you're clearing it, amber means on track, red means at risk. It updates as you practise, so you always know what to study next.
Confidence calibration
When you rate how sure you are before revealing an answer, we learn where you're confidently wrong (dangerous gaps) and where you're right but unsure (shaky). Those topics get flagged and pushed to the front of your weak spots — something most prep tools never measure.
The Review hub
One place for everything you've already touched: Due today (spaced repetition), Incorrect (everything you've gotten wrong), and Flagged (your bookmarks). Each is a one-tap review session.
Mock Exam
A full 120-question, 150-minute simulation, blueprint-weighted to match the real OPRA. The timer is exam-accurate (it keeps running even if you close the tab) and you can resume an interrupted attempt. You get a pass/fail, a domain breakdown, and one-tap links to drill your weak areas.
Calculations Lab
Randomised numerical questions across the full OPRA calculations blueprint — dosing, dilutions, rates, conversions — so the maths becomes automatic. Free forever.
