Yes it is normal. How important your ITE is to you and your program depends on your PD and how 'serious' you about your boards.
You: Early on it is hard to do well on-unless you have been crazily studying as a medical student, already have inside knowledge on the best study aids, or some other advantage-one of those people that are so annoying who just take tests well.
To me the main advantage was it that is a stark dose of reality early on and now you know what the end goal is for your residency. You will have to pass the test to do well.
At my program there is a heavy emphasis on board scores right from the 'get-go' and there are big incentives to do well, even early on.
We are not allowed to moonlight if our scores are not over the 50th percentile. If that isn't enough it is also introduced into our overall performance, as one of two major factors, the other being overall clinical evalation which is very subjective.
Doing well on the previous exam sometimes can be our only safety net if we haved pissed of some miserable attending on an eval.
So, bottom line, talk to your upper levels, and see how heavily your PD is concerned with your ITE scores, otherwise chill and enjoy residency.
