No exam here is written from one book.
Some boards name the texts they write their questions from. Others build the exam from a study of what people in the job do. Our questions cite their sources, and every answer prints its source so you can look it up.
“The Certification Examination Reference Lists contain the texts used to develop the questions for the certification examinations.”NBSTSA, 2025 CST Candidate Handbook
“NCSBN performs an analysis of those activities used frequently and identified as important by entry-level nurses to ensure client safety. This is called a practice analysis; it provides data to support the NCLEX as a reliable, valid measure of competent, entry-level nursing practice.”NCSBN, 2026 NCLEX-RN Test Plan
What happens when you press Practice
It looks simple because the work happens behind it. Every set is built for you from everything you have answered so far.
It finds your level
Questions are aimed so you get about 3 in 4 right. As you get better, they get harder.
Every question knows how hard it is
From how every student answered it the first time, and it keeps updating.
Your misses come back
Miss one and it returns later, once you’ve had time to learn it.
It leans on your weak areas
An area under the pass mark or below the passing standard gets more of your practice until it catches up.
The exam is built like the real one
The real length and clock, dealt by area in the official outline’s shares. A timed exam lets you skip, flag and go back; an adaptive one asks one question at a time.
One score, and what to do next
Each question counted once, by your first answer, against the pass mark or the passing standard, with one sentence on what to work on.
Frequently asked

Ask a questionIs it free?
Five new questions a day for each exam, the same five for everyone, with the answers explained. No account needed. Pro opens every question and the full exam for every exam.
Which exam should I pick?
The one you are sitting. A surgical tech student usually sits the CST or the TS-C; sterile processing, the CRCST or the CSPDT; a first assistant, the CSFA; a nursing student, the NCLEX-RN for registered nurses or the NCLEX-PN for practical and vocational nurses. Pro opens all of them, so you can switch.
Does it match the real exam?
Each timed exam has the real length and clock, and deals its questions by area in the same shares as the board's official outline. An adaptive exam asks one question at a time and stops when it is sure, like the real one. The NCLEX practice tests ask more than multiple choice, as the real one does: case studies, bow-tie, matrix, highlight, drop-down, select all that apply, grouping and calculation.
How do I know when I'm ready?
Watch one number: your score, which counts each question by your first answer to it. When it stays over the pass mark, sit the full exam. On an adaptive exam, watch how likely you are to pass instead.
One plan, every exam.
