How is a 620 on the Barron's ?

<p>Hi there. So my SAT Subject Tests are just three days away, and I have begun taking practice tests from Barrons. And I just got a 620 on a Math 2 Model Paper (From Barron's). I have heard it is harder, but I just wanted to ask if anyone knew what a 620 on it would translate to on Test day ? :)
Thanks. :)</p>
