There are two Hesi tests. The first is the Hesi A2 entrance exam which is basic math, english, reading comp, biology, chemistry, and A&P. Not all schools test on all areas. Then there is the Hesi exit exam you take while you are in or leaving the nursing program and its nursing stuff like the NCLEX.
You need to call the school where you will be taking the test and find out what areas they test on. Then go to
