<p>I bought a Barron’s book thinking it would challenge me and help me get an 800. However, Barron’s is brutally hard. Almost every question in it is a harder question. 620-650 is pretty good but if you want to get in the high 700s, you should aim to get a 700 on the next practice. </p>
<p>I would suggest that if you are taking the Math 2 test, you aim for an 800. Many other high achievers take this test, so a 790 is only the 89th percentile.</p>
