<p>I took Ic the first time and got a measly 640. I've heard that the scale on IIc is much more forgiving and easy to score high on if you know your stuff but the fact is I'm not sure I do. I passed with a B in Pre-Calc and I found it difficult to remember all of the concepts for the final in the class. I'm just overall not very solid in math and don't want to blow my last chance taking the IIc if I won't do well. </p>
<p>Very generally what kind of things do I need to know for IIc? I heard that a TI-89 with a few programs can help a lot but I don't have a TI-89. Is it possible to do very bad if you took all the classes and passed with decent grades but are not solid with the concepts?</p>
<p>I'm in the high 700's on the SATI math so I'm fundamentally set with Ic I believe but the small mistakes on Ic hurt a lot. </p>
<p>What would you recommend for a person like me? I'm not by any means bad at math, and I'm probably being overly cautious but I just can't afford any wrong choices at this point.</p>
<p>Thanks A LOT to any one who can help me out, my appreciation cannot be translated into words..</p>
