Are you sure the HESI is your entrance exam and not an exit exam? Unless it is a different version, I dont see how anyone could be expected to pass the HESI without having already gone through the majority of the nursing program.
I just graduated from TWU Dallas and we took HESI about a month and a half before graduation. It was a VERY big deal... it was difficult and there were several people who didnt pass on the first attempt.
In my experience, most schools require the NET as the entrance exam-- that's just basic math/english/etc... pretty easy.
If it IS a HESI exam that you have to take, I think the website is Evolve
. They had a great review book for the exit exam, so Im sure they'll have something that you can use to review for an entrance exam if that's what you have to take.
