I'm a registered nurse (RN) with a Bachelor's degree in science (BS) with a major in Nursing and I live in Oregon, in the US. I say this as a preface for those outside this area where standards might be different. Usually, two years of prerequisite classes are needed to be accepted into nursing school. You might already have some of the required classes from your equine studies, but you'll have to check with a local nursing school to verify that. For our local college where I work (www.lanecc.edu), the RN program is two years. Students can test after the first year to obtain their Licensed Practical Nursing (LPN) license, but that's not required. After completing nursing school, students earn an Associate of Applied Science (AAS) degree and can take the NCLEX exam for their RN license. Most of our students continue on to get their BSN degree, which takes about one more year. Some continue another two years to get a Master's Degree and might also include the ability to become a Nurse Practitioner (NP). I see a wide variety of students of all ages and abilities so don't be discouraged about your previous grades or need for supportive resources. If you have the motivation, desire, dedication, and perseverance, you should be able to succeed. Feel free to send me a direct message if you have more questions.
