Do I have to take the exam?
The short answer is maybe. A majority of nursing programs require successful completion of the HESI A2 exam for entrance into their nursing program. Every program has different admission requirements – some require all seven subtests, while others require four or five subtests. The best answer to this question is to follow the application directions for the program you are applying to, and if you have any questions, contact the registrar of your college or university for guidance.
How do I register and schedule the exam, and what does it cost?
Your program advisor will guide you with the registration process. Often the exam is offered on the campus of your nursing program. Dates, time, and cost vary by institution. Your program advisor will assist you with registration (usually online), which tests to take, when the test is given, and cost.
How long is the Biology subtest?
The subtest is delivered by computer and consists of 30 multiple-choice questions. Five exam questions are used for evaluation in future exams and do not count toward, or against, your score. You are unable to distinguish between the scored and non-scored questions. Each question is followed by four possible answers. You must select the correct response to receive credit for the question. Each question has only one right answer.
You have 25 minutes to complete the exam. You have about 50 seconds to spend on each question, so pay attention to your time that remains. If a question is proving to be difficult, make your best guess and move on. If time remains, you can go back to prompts that you are unsure. An on-screen calculator is available for your use.
