<p>How similar to the actual SAT in difficulty/style are the 10 Collegeboard practice tests offered in the Official Blue Book? </p>
<p>I've been getting decent scores on them, and I'd like to know if the actual test is actually more difficult compared to the ones given in the back of the book, reliable in terms of actual test difficulty, or even (unfortunately) easier than the actual thing.</p>
<p>Thanks in advance.</p>
