Barron's or John Chung's Math Level 2?

<p>Hi guys. I've read so many posts, saying that John Chung's Math Level 2 book has the hardest practice tests, even harder than Barron's does... but... The maximum I've got from Barron's was 650 while from John Chung's Math book I've got 760.
Right now I just don't know if I should be calm or a bit nervous..
So which one is harder? Barron's or John Chung's tests?</p>

<p>Why do you care? The actual test is easy…</p>
