<p>I'm taking biology and physics this saturday, and I have no book to study from. I used sparknotes to learn the concepts (plus I took the respective classes), but in search for practice test I found sample questions from collegeboard.com.</p>
<p>SAT</a> Subject Test in Biology</p>
<p>SAT</a> Subject Test in Physics</p>
<p>How accurate are they in regards to the real test? Are they easier? Harder? About the same? If I miss none or just one on these sample tests, can I predict the ballpark of what score I am aiming at in the real SAT test?</p>
