No, the real thing is unique b/c the questions and longer and harder than the NBMEs; the material has a different focus (more molecular **** that people don't know that well, as well as more stuff not in FA); and most of all, b/c it's real, ie you see that clock ticking down and actually care/start to panic;
Everyone's situation is different and everyone gets different test forms. That's why the test can be an unfair/inaccurate judge of how much one knows especially when you get into the 250+ range.
The test can go 3 ways
1) your weaknesses are a lot more emphasized than your strengths - leads to under-performance
2) strengths and weaknesses about equal - expected performance
3) your lucky day and strengths over-emphasized - ecstatic and unbelievably surprising performanced
My exam for the most part had questions similar to the NBME's. The large majority of the questions had short or medium stems. I did not get a lot of molecular stuff at all and had maybe 2 or 3 questions that were completely new to me and fell outside the wonderful triad of FA, RR, and UW.
I believe timing is something that comes with practice with a natural element as well.
People who are good test takers tend to panic less and use time wisely -
1) an easy question should be done quickly but not in a hurry - if it seems too easy a quick doublecheck of a stem that doesn't take much time and then move on
2) hard and ridiculous questions should be skipped the 1st time thru and come back to after you do all the questions you "should" know
3) medium questions and questions that are easy but take time to figure out - these are where more of your time should go
I'm willing to bet people who did 3,000+ questions and multiple assessments had less timing issues than others. I finished every block with at least a few mins to spare, most 5+. I'm not a notoriously fast test taker as I usually finished class exams in the middle of the pack but I trained my mind for the test - most of the questions are pretty predictable after time
Step 1 is a beatable test and much more reasonable than the MCAT granted you don't get an unfairly difficult test that also happens to emphasize your weaknesses.
Many people who were considered poor test takers because of a MCAT in the 20's happen to score 240+
