Is prometric practice session worth it ?!

If you're taking your exam soon then you're already considering whether to take the practice test at the prometric center. The test, at least in my country, costs almost 200 $ which is quite expensive, don't you think ?
So let's take a look at it and see the pros and cons:

Pros:

mimic the test day experience exactly.
test the noise canceling headphones.
try layer dressing and the air conditioning.
see the security measures and what they will ask you to do when you're about to enter.

Cons:

$$$

Verdict:

If you're on a tight budget, better use that money to buy 3 or 4 NBME forms that can really predict your score and give you a confidence booster. If you have the money then you'd better take it. Don't worry, if you can't or won't take it you can go to the prometric a couple of days before the exam and see the transportations and ask about whatever you want there. The staff there are really helpful and they will help you.
