I'm taking my first two years online from an ivy league extension and then doing 4 years on campus. I think taking the extra couple years is great because 1) spend some time with family 2) more time to volunteer ect and strengthen app 3) work 4) add two years of youth to your life
like idc about becoming a neonatologist when I'm 34 instead of 32 if you catch wat I'm saying.. but getting an extra couple years at this age is golden... not only that but it will strengthen my app... and I'm doing this on the front-end of my undergrad, not back end.
It's funny you mention this I was thinking about adding another year and semester to the 4 years of undergard, to work on ECs, get more research and clinical experience, take more classes that will be interesting. I had the same reasoning as yours well what is 32 to 34 anyway. I decided that for me it wasn't the very best option (though I'm still considering it).
1st Time is precious! You can't waist it what's 32 to 34 (hmmm..... time spent paying off debt, having a family, making friends or reconnecting with old ones, becoming familiar with my work and gaining experience as a physician, etc.)
2nd In that two years you have so much opportunity to do OTHER things. Say that you wanted to become a Fulbright, Marshall, Rhodes scholarship or you just decided to go abroad or just travel around the states. I'm sure this is better than kicking it at an undergrad which after a few years WILL get old! Now that's more years your adding what's 32 to 37 (a five year old son or daughter, a decent sum of debt payed off, an established private practice).
3rd What if you don't get into med school even after the 6 years of undergrad? Are you gonna pursue a master or SMP (which is more debt)? Are you gonna work and reapply? now what's 35 to 32 (assuming you get in at all). (A helluva lot of other things you could be doing)
All in all I think taking an additional year is fathomable (but still not preferable). 2 years is a LOT of time especially if your a quarter million in the hole.
IMO, just shoot for the regular for, If all else fails pick up a minor senior if you don't get accepted and there's your additional year.
