<p>Quick question for those of you who took the Biology Subject GRE, how much more difficult, if at all, is the GRE exam vs. the one in the practice booklet put out by ETS. Putting aside things like time pressure/different environment/nerves, how different should I be expecting my mark to be, on average, from the practice to the real thing. In other words, is ETS making the one in the booklet easier --> more people take it, but the exam is actually much more detailed? </p>
<p>Thanks.</p>
