First of all, congratulations on your goals!
I had several years of nursing under my belt when I applied to med school, and am now in my 4th yr, applying for residency spots.
It's not easy to make the transition, and I think there's been great advice on flying a little below the radar and how nursing gives us an advantage as med students (as far as practical interviewing, physical exam and procedural skills go). Needless to say, you will rock third year, and it's a very important year!
It can be tough to keep one's mouth shut, though.
I found the hardest parts to get over were:
1.) the lack of real world, hands on work during the first two years. I definitely had developed learning skills that were based on seeing and doing while being a nurse - it made reading more poignant. The first 2 yrs of med school are, unfortunately, reading reading and more reading. It was hard for me to make the transition back to purely classroom based learning. (Even if you do case based learning, the cases that are devised are never really true to life!)
2.) being older and wishing at times that I had gone to med school sooner. But, I wouldn't be where I am if I hadn't been a nurse.
3.) The much grieved loss of a steady and pretty decent paycheck.
Still waiting on this one!
But, once you get back to the clinical rotations, it's all worth it. You will be amazed at how much you've grown, not only in terms of the knowledge gained, but in terms of your perspective on life and the benefit of working harder than you ever thought you could.
What does amaze me, and what I hadn't expected, is that now, as I show people my CV and discuss future career goals, they are generally very shocked and surprisingly impressed about my
former career and the fact that I decided to go to med school. Maybe it shows them a different kind of gusto? Maybe it lets them know you'll be great clinically? Maybe it's just proof of dedication? I don't really know, but I am taking it all in stride! That can maybe help withstand a lot of the **** that floats in the proverbial toilet bowl of the first two yrs.
If you get into the conversation with seemingly hostile admissions committees, you can say that while you're glad you were a nurse, that it prepared you in certain ways for the practice of medicine, you
do need med school to achieve your dreams, and you have lots to learn, etc. It will help take some of the hostility out of the equation. And it's not entirely untrue, right? It just might suck to have to give in a little to manipulate that specific situation.
Another thing to keep in mind:
I am a lot happier and less stressed about the whole path to becoming an MD than some of my more naive counterparts, b/c I know what it is like to be in a job I didn't exactly love. But now, I am 110% sure that I was meant to be an MD. It feels good and takes a lot of stress off your shoulders when you can be certain you've picked the right goals, and it gets you through the rougher patches.
Good Luck!
