PSAT Practice test difficulty compared to PSAT

<p>I'm now taking the PSAT as a Junior in hopes of becoming a National Merit Finalist. I took both the SAT and ACT in freshman year and without studying, i got a 1760 on my SAT compared to a 29 on the ACT, so i've stuck to the ACT ever since.</p>

<p>However, as the PSAT is looming on Saturday, i decided to start studying tonight and just did the math portion of the practice test that the school gave me when i applied for the PSAT. I got a 77 on the Math ( Only got this one incredibly BS question wrong.) So, math is my strong suit but I was surprised I scored this highly and this makes me confident for saturday, but...</p>

<p>Is the PSAT Practice Test generally easier or the same as the actual PSAT?</p>

<p>Also is the PSAT a good measure for success on the SAT, cause if so, I might want to take another SAT again to see how i do.</p>
