If you feel uneasy now, chances are you might feel overwhelmed in class day one.
There are some who drop out the first day, then week two, three, etc.
Remember circumstances change.
It is hard to concentrate when you are upset, so I can suggest study groups (try more than one until you meet with a meaningful group), because there is safety in numbers. When you join one, listen, and do not worry if you do not know the answers, don't spend more than 5 minutes discussing fears (there are time constraints that involve childcare, employment, and bill paying, grocery store runs for each member).
Move on to the first subject, bring highlighters, pencils, and paper until you find your own notetaking ability.
Ask your instructors if you can record today's class whenever you start class instruction. Take notes in class too. Write whatever the instructor writes on the overhead, board, or verbally spends time on.
Read some assignments ahead of class and keep up on the reading because it takes time for the information to sink in, put the book down, do a chore or pay a bill, and pick it up again, after a while it will start to click.
Best of all listen, because some classmates may have a simple explanation that will help you remember, do not purchase unnecessary books either, just the required ones.
Reward yourself for courage to ask for help and do not stop doing this when necessary as it is a lifelong process.
Use one on one study sessions or study groups.
Come early, and practice in labs, read today's assignment a little more.
Practice in labs as often as you can and bring your book.
Watch your CD Rom to learn techniques that help save lives, and remember the people in the picture practiced before the camera was switched on. Anything can be edited to perfection in computerland.
Mark your books with your name, do not loan unless you can get your book back. If you are uncomfortable with study groups due to humility than I suggest you swallow your pride, and open your eyes and mind.
Plus be sure where the nearest restroom is nearby at all times, because your instructor and classmates will appreciate that you have a disposition, but you are able to control it.
And when a smart***, know it all, asks why did you enroll in nursing?
Do not entertain mr., mrs., or ms legacy, class A student, or the outright disruptive jealous individual (yes, you make people jealous intentional or not, do not let it go to your head or take advantage of others in the wrong way, and remember there are people who will be manipulative throughout the course).
Just move on, stick with it, it will make sense........God Bless, Good Luck.
