<p>I'm in Precalc too. I wish I had your book! I took a summer course to skip Trigonometry and that was basically the format and I LOVED it. We now have this crappy book with lots of concept based learning and word problems. It's time consuming AND vague. I mean I'm a humanities girl all the way through but I find that math is math, the beauty of math is the logic and conciseness of it. </p>
<p>On the other hand, lots of people do much better with concept based math... if you're one of those people you should probably move down a level.</p>
