HESI A2
Sections vary by school — may not need all
Individual section scores let you see specific strengths
Some schools allow unlimited retakes

🏆 The Verdict
Choose the TEAS if: Your program accepts it, you want a standardized format, and you prefer focusing on 4 clear sections with strong study materials available.
Choose the HESI if: Your program requires it specifically, you're strong in sciences (Biology, Chemistry), and you prefer individual section scoring.
Bottom line: Most nursing programs accept the TEAS, and it has more standardized study resources. If your program accepts either, the TEAS is generally the safer choice for first-time test takers.
