<p>Thanks. How long have you been working at it Trufflie?</p>
<p>It was very systematic. During each test I would circle the ones I was unsure of, even if I knew the right answer or thought I did. Then, afterwards, I would review not only my wrong answers but the ones I circled. All of them were from the blue collegeboard book so I could look up answer explanations on their website (I can’t remember the URL right now, I assume you have the book).</p>
