<p>I am in Calculus but I got a 300 on my Barron’s diagnostic test. I got a 25 on the ACT math section, so I think I know most of algebra, geometry and trig. I also don’t really understand how the Barrons book explains it. Are there any online study guides that could help me for last minute prep? (I’m taking it May 3rd).</p>
<p>I’ve heard Barron’s is a bit harder, but a score of 300 on the [200, 800] scale likely indicates that you’re not ready for Math II, or you were pretty much passed out during the diagnostic test (since you scored 25 on the ACT math – you should be capable of 500-600+ easily).</p>
<p>From what I’ve seen, test prep books are generally fairly good at explanations (except for rare instances where I’ve seen typos or other mistakes on problems), so try reading the explanation again, slowly, making sure you understand everything in the explanation. Work through the problem simultaneously. If you still don’t understand, feel free to post the problem/explanation here.</p>
<p>Yes, Barron’s tests are significantly harder than the real SAT Math II tests, both the released tests and the actual exams. What I don’t know is how well Barron’s scores correlate with scores that one would obtain on a real test. </p>
<p>Why not take Math I?</p>
<p>Harsher scoring curve, usually.</p>
<p>Math I- 680
Math II- 780</p>
<p>That’s what I got. Explains the harsh scoring curve. </p>
<p>However the [200, 800] score might not mean as much as the percentile. For example, an 800 on Math II is only around the 85%ile, while a 720 on Math I is also 85%ile. Interestingly, you can miss a ton of questions on Math II and still score 800 (I honestly don’t know why they don’t increase that parameter), and the populations taking Math I and Math II are quite different. Confusing.</p>
