<p>Do people usually take 3 subject tests in one sitting? How difficult is it to do? How big of a factor is fatigue? Thanks</p>
<p>lol it's not bad at all. the subject tests aren't very long and hard so they're not very tiring imo. as long as you've prepared enough, you won't have a problem.</p>
<p>Each one is only an hour long and it's not as fatiguing as taking the regular SAT. It is certainly doable.</p>
<p>Personally, I did one, then two several months later. A lot of people choose to do three, but I would have found that taxing, especially after Literature, which drained me.</p>
<p>I did 3 in one sitting and actually my scores increased (first test was worst, last test was best)</p>
<p>I did three at once and did not find it bad at all.
However, if you have plenty of time remaining before you have to send in your scores, and you feel like fatigue might be a problem (or you just want to study one thing at a time) there's certainly no harm in taking them separately. I have a friend who did this...but most people I know just do three at once, and it doesn't seem to hurt them.</p>
<p>I did three in one sitting. I took them in order of most worrisome to easiest:</p>
<p>Math II: 800
Bio Molecular: 770
Chemistry:790</p>
<p>Fatigue is not a factor at all unlike the normal SAT.</p>
