I am currently in my 4th year of Medical School, just thought I would offer the “insiders” perspective.
It takes a year to apply, so if your Fi currently has all of pre-req’s done (he can look those up), and starts getting his letters of rec, and takes the MCAT this year, the EARLIEST he would be applying is NEXT (2012) year (it is too late to apply this year), which would mean he would be starting Med School at the EARLIEST August of 2013.
So, in my opinion, he should take a good paying job and start getting everything in a row for applications next summer (or start taking his pre-req’s which usually take about 2 years to finish if you didn’t do them while in college). Start saving now–applications are expensive (I think i spent about 3k between applications and interviews, i had 7 interviews out of 35 schools applied to)
All that being said, once he starts medical school, the first 2 years will be ALL book work, and the 3rd and 4th years will be clinical, ie in the hospital.
He will be recieving financial aid (almost all of us get 100% covered, our school and living expenses.) Few of us come from familys that can afford to pay for our schooling (certainly don’t), we all leave with about $150,000 in debt ( that is the national average, I will have close to double that), and everyone manages to pay it off. People think doctors make TONS of money, but really if you look at the years we spend in school not getting paid and accumulating massive amounts of debt, its not a very smart career dicision if you are going into it for the money–you need to have the love of caring for patients.
Ok, so all that being said, I think it is a LOT easier for men in Med school to have children than it is for the Women. Almost all the guys in my class that have had children have wives that pick up the slack–some wives work, some don’t and they are just very good at streching their financial aid.
During the first 2 years your Fi will be home a lot more often, he would be able to help because he will most likely be home studying. During years 3 and 4, it will be harder, he will be working long hours, usually 10 hour days on some roatations, but then on others he will get 4 day weekends (at least that is how it is at most schools I know).
I agree with the above comment, I think it is easier to have kids in Med school than during residency–depending on which year you decide to have kids.
I hope this helps, all of this is just what i have seen from my 4 years of med school and the residents that I know. If you have any questions please feel free to ask!
