I just finished algebra 1 over this summer, pathetic I know. It's the price I gotta pay for messing up in high school and taking two years off afterwards. I start Algebra 2 in the fall and I'm going to take PreCalc over winter break. Does anyone recommend any books or materials I can use to further prepare for Algebra 2, especially PreCalc. My teacher told me it's a lot of trig. I have next to no experience with trig. In high school I took geometry but didn't do so good in it. Would Algebra 2 be sufficient preparation? The PreCalc class will be five days a week for twelve days. I know its overkill but it has to get done.
