Encodr helps you actually hold onto the material this margin depends on - spaced-repetition flashcards for exam prep, not just one-time cramming.
Get started freeA fixed passing percentage - 70% is common on many licensing and certification exams - feels close to "get almost everything right" until you convert it into an actual number of allowed misses. On a 150-question exam at 70%, that's 45 questions you can miss and still pass, which reframes the exam from "don't mess up" to "here's your real margin." Some licensing exams, including many state insurance exams, also seed a small number of unscored pretest questions that look identical to scored ones - since you can't identify which ones those are, treat every question as if it counts and use your official score report for the real scored total.
