Barrons BC calc hard?

<p>Ive taken a couple of practice tests and havent done too well on them. If I am getting in the 4-ish range, would you say I would be able to get a 5? Also, how do Petersons and Princeton Review's Practice Test compare to the real exam?</p>

<p>Thanks</p>

<p>I heard Barrons is harder and if its a high 4 I would think your good.</p>
