I agree fully with Mango. We have had 10 people quit this year already because it isnt 'what they expected.' The first year you are taught by PhD's, the second gets better being more clinically oriented and taught by MD's. Then 3rd/4th year hits and you are on call all the time. And talking to the residence seems to be overly depressing.
So, am I going to quit while I am still ahead? HECK NO! I do agree that you should have clinical experience before applying. Why do you want to be a MD if you have no idea what it is all about..pressure at home, money (which I hope isnt the case)?
Anyway, I worked in the ER for 3 years in undergrad as a nurse assistant. No matter how 'scut' the work is in 3rd/4th year, it cant match up to what I did as a nurse assistant. And despite all that, I am actually missing working in the ER. I miss the patients and the clinical work.
Of course, I am not near residency yet, but I absolutely LOVE medical school. Maybe because it was something I worked at for a long time and I am finally here, but the team work and the closeness to your fellow classmates is so rewarding.
I say this alot, but I do think that you can help out your 4 years by researching the medical schools that you are applying to. They are all very different(competition between students, size of class, ect)
and that can affect how you will adjust to the school. As for residency, unfortunately, it is something that we all have to hurdle over and the issues are in continuous debate about the lack of sleep and the saftey of the patients. Who knows, maybe one day things will change, but for now, you have to know what is ahead and knowing this and accepting it is very important in your attitude and adjustment when you get there.
I hope this helps
