Good luck - heads up if you get admitted . You will need some money! Its about 3000 altogether. Book package, uniform, tools needed and background check, medical check , vaccines plus your tuition, Wish someone had told me and I would have saved a bit for it!
HESI is not bad - math dude on you tube and nurse hub helped me a lot . Just keep practice and you will do fine. Critical thinking is like scenarios in hospital settings and what is the best answer. keep up math for meds you will need them at beginning of semester .
