Getting 90s on practice tests and still failing the written exam?

A practice score can measure the wrong thing

Take the same practice test twice and your second score will usually go up. Some of that is real learning. Some of it is recognition: you remember that the answer to question 14 was C, or that a particular option was right last time. The real exam gives you none of that help, because every question on it is new to you.

So a score you earn on a test you have already seen tells you less than the same score on a test you have never seen. The second number is the one that predicts the day.

What our own practice data shows

We looked at NICPrep users who took the same practice test more than once. On the second attempt at the same test, the average score rose by about two points. Among the 14 people who took the same test five or more times, the average climbed from 85% on the first attempt to 89% by the fifth and 91% by the sixth. Those later scores were earned on questions they had already answered.

Why repeated questions make it worse

Many free and low-cost study tools draw from a small pool of questions. If the same few dozen keep coming back, a rising score is mostly a memory test. Candidates who fail often describe the same pattern: an app that keeps serving the questions they have already seen, a flashcard deck that looks nothing like the real paper, and a real-exam score that barely moves no matter how many practice tests they take.

The written exam is built from a published content outline, with each topic area, or domain, given a fixed share of the questions. A practice source that ignores those proportions can leave you strong in the topics you like and weak in the ones the exam weights most.

How to tell whether you are actually ready

1. Judge yourself on a first attempt at a test you have not seen. That score is the honest one. Save at least one full test you have never opened for the week before your exam.
2. Look at your score by domain, not just the total. A 78% overall can hide a 50% in a domain the real exam weights heavily. Find your weakest domain and spend your next study session there.
3. Practise at the real length and pace. Your candidate bulletin gives the question count and time limit. Sit at least one full-length test under those conditions, in one go.
4. Learn the vocabulary, not the answers. Many misses come from terms that look or sound alike, especially scientific ones. Our free terminology drill covers 862 terms the written exams use, filterable by exam, with no account needed.
5. When you retake a test, retake it for the explanations. Read why each wrong option is wrong. Do not use the rising number as a sign you are ready.

Why we build our practice tests this way

Our NIC and state prep banks give you ten separate full-length tests per exam (twenty for Florida), built to your exam's published content outline, so you can keep testing yourself on questions you have not seen. Every question comes with a full explanation of why the right answer is right and why each of the others is not, and you can see your score broken down by domain after every test.
