The HESI Admission Assessment (A2) Exam, published by Elsevier, is used by many nursing and allied health programs as an entrance exam alongside or instead of the ATI TEAS. The full exam has up to 8 possible sections: Reading Comprehension, Vocabulary and General Knowledge, Grammar, Mathematics, Biology, Chemistry, Anatomy and Physiology, and Physics. Unlike the TEAS, the HESI A2 is modular, each nursing program chooses which sections applicants must complete, and most programs only require 4 to 5 of the 8.
Because HESI A2 sections are typically scored and reported individually to your program, and math sections often include dosage-style calculations relevant to nursing specifically, practicing the actual question formats builds both the academic skills and the nursing-context comfort the real test rewards.

About the real test
The HESI A2 has up to 8 possible sections, but it's modular, each nursing program picks which ones applicants must complete. Most require only 4-5, most commonly Reading, Vocabulary, Grammar, Math, and Anatomy and Physiology.
Confirm your program's exact required sections first
Don't assume you need all 8 sections. Check your specific program's requirements before deciding how much to study biology, chemistry, or physics.
Math often includes dosage-style calculations
Unlike a general math test, HESI A2 math leans into medication and IV-rate style calculations relevant to nursing. Practice those specifically, not just general arithmetic.
Anatomy and Physiology is the most commonly required science section
If your program only requires one science section, it's most often A&P, not biology, chemistry, or physics.
