Can anyone help me and point me in the right direction?

Hi everyone! A little about me: My name is Kristina and I have two beautiful babies, Paul jr 5 and Chloe Alexis almost 3. I live in Indiana and I'm 25 soon to be 26 next month. I recently decided to go back to school and I couldn't decide if I wanted to become an elementary teacher or a nurse. The reason I decided either was for the simple fact of wanting to be more hands on and wanting to help people. Ok, so I think I decided to become an LPN and I think it would be the best route for me. My husband works full-time at Toyota and I know becoming an LPN only takes about a year (give or take) and If I wanted to further my education to an RN I know I could still earn an income doing so. Right now I'm a full-time mom and only have my high school diploma...no college experience what so ever. My questions for you are (and I really do apologize if these were answered already, I tried going through SOOO many threads and some of them were questioned and some not) anyway, I really don't know where I would start...I know I want to attend the LPN program at Ivy Tech in Columbus but I don't know (like I've said) where I start. Do I have to take any classes before I apply or are all the classes that I have to take in the program? Do I have to take some kind of test before they will allow me to apply to the program? I mean I really am lost lol. I'm nervous thinking and talking about going back to school because I've been out for 7 years lol. I know that I'm nervous about not being good enough to become a nurse but I DO know that I'm a kind person and I love helping people! I use to work at a place in my hometown in Ohio helping the physically challenged do a job (like count and make boxes for a company) to earn a paycheck. I know it wasn't a whole lot but I enjoyed seeing them be excited about doing a job to earn their own money, it was very rewarding. Anyway, I really appreciate you guys looking at my thread and helping me out. Best of luck to all of you in whatever you do!
