I am a 3rd term student at Hondros Columbus. You will like this school alot, instructors are great and make learning quite fun. As far as the HESI just buy the study guide book and really practice the problems. If I rememer correctly, its a 4 parter. If its been awhile since you have had a math class, make sure you practice the problems. Its amazing what you forget after you have been out of school. Good luck and I hope you excel!
