Keslaly Tip: Keslaly covers all 9 HESI A2 subjects with exam-style questions and detailed explanations!
Study Smart – Use high-quality, exam-style questions.
Time Yourself – Take timed practice tests to improve speed.
Understand, Don't Memorize – Focus on concept mastery instead of rote learning.
Track Progress – Identify weak areas and improve strategically.
Keslaly Tip: Keslaly gives you all four — exam-style questions, timed tests, detailed explanations, and progress tracking.
The HESI A2 is challenging because it tests a broad range of academic skills, but with proper preparation, you can pass with confidence. The difficulty level depends on your study habits and familiarity with the subjects.
Keslaly Tip: We provide exam-style questions and step-by-step explanations to make studying easier!
Each nursing school sets its own passing score, but most require at least 75%-85% per section. Some competitive programs expect 90%+ in key subjects like math and science.
Keslaly Tip: With our performance tracking, you can measure progress and aim for top scores!
The HESI A2 and NCLEX serve different purposes: HESI A2: An entrance exam testing academic knowledge. NCLEX: A licensure exam testing clinical decision-making. It is therefore not reasonable to compare the two exams in terms of difficulty.
Keslaly Tip: Ace the HESI A2 with us and set yourself up for NCLEX success later!
The NCLEX-RN is widely considered the most difficult nursing exam, as it determines licensure and requires critical thinking and application of nursing knowledge. However, the HESI A2 is challenging because it determines your entry into nursing school.
Keslaly Tip: We help you conquer every step of your nursing journey—HESI now, NCLEX later!
If you fail the HESI A2, most schools allow retakes after a waiting period, usually 30 to 60 days. Some schools limit the number of attempts per year.
Keslaly Tip: Our targeted study plans help you pass on your first try—no need for retakes!
An acceptable score varies by program, but most schools require at least 75%-80% per section. Top-tier programs prefer 85% or higher.
