<p>Hello guys, Im planning to register for my SAT subject tests in the Fall of October 2009 and they’re Biology M and US History.</p>
<p>My question is whether or not if it’s true cause some people told me that October SATs are usually more difficult than those of November and December. Can anyone get this straight for me? How difficult would the Biology and US History exams be if I just study from Barron’s red book and skim through Sparknotes?</p>
<p>Also, is the US History SAT curve suppose to be more lenient (+) than that of World History’s?</p>
