Formula-recall trainer
A formula-recall trainer for SOA Exam P and Exam FM: prompt face-up, formula hidden, self-graded - the format that builds recall rather than recognition.
140 prompts - 82 for Exam P and 58 for Exam FM. Every card is generated from the same record its formula page renders, so a card can never state a formula the page disagrees with. A fresh 10-card deck is free every day.
