and provide 3 simulated residency interviews along with extensive feedback on presentation skills?
I mean, if you want a serious answer, I guess I can give you one. The big questions is, who is giving you this advice? A med student? An undergrad? A resident? I would request to see the CV of the person you are paying for. Secondly:
"and
your personal statement is almost as important as your Step 1 score in deciding whether you are invited to interview."
This is total, unequivocal, bull****.
If I am paying $2,000, I want the program director at a top 10 program to be giving me advice. That said, any PD who is working for Kaplan on the side probably is not all that credible. Otherwise you might as well see your own advisors at your home program that you are already indirectly paying for.
The interview is important, this is true. But you are a ~27 year old adult, you pretty much are who you are. Can you practice and get a few pointers? Of course, but your personality is not going to fundamentally change. I think a friend/colleague/advisor asking you common interview questions will be almost as effective.
In summary, I am 95% confident that I am equally or more qualified to help you than the people at Kaplan, and my $1,000 price is a bargain.
