You want to make sure this is something you want to do and invest your time looking up information about nursing. Look at the pros and cons of being a nurse. Nursing can be a rewarding career, but there are times when it will get very hard.
2. Research the program/school you want to attend.
There are two types of programs you can start with: there is the Associates in Nursing (ASN) or the Bachelors in Nursing (BSN). After you have decided on a program then the next step is to talk to an advisor or research what type of classes that is required to take before entering the program. Some schools only require the entrance exam and the science core classes (A&P, Micro...) taken while your attending the program.
3. Good grades are important.
Good grades are very important because most nursing programs are competitive and limited access. Depending on the school they will most likely choose the person with the higher GPA. For example, I wanted to attend a BSN program that was very competitive. I had a 3.57 GPA and was told by my advisor that it was good but not really high enough. The average people who entered the program had a GPA higher than 3.65. So, I decided to stick with an ASN program and later on transfer to a BSN program.
4. Study for your entrance exam.
Take the time to study a few months before the test. Do not wait 3-4 months after you have finished your prerequisites to study for the test. You want to study close to the time you have finished your prereqs or while your still taking your classes. It's good to study the teas or hesi while things are still fresh in your mind. Do not wait until the last minute to study for the exam either because there's a chance that your test results might not look so pretty.
5. Time management.
Start now and start making it a habit.
6. Saving money.
Nursing school is time-consuming and there may not be much room to work. So, while your taking your prereqs start saving. Also try to apply for grants and scholarship.
