<p>Well currently I am taking classes for math IIC and Bio. My math class is based on the ti-89 calculator and guarantee a 150-200 point increase after learning it's calculator functions that they provide you. This is a blessing to have, but I am struggling on just knowing how to do problems that the calculator can not do. I am currently in algebra II as a junior so I haven't learned a lot of the concepts that are on the test. What book could I purchase that will help me catch up with a lot of the concepts that are needed for the test?</p>
<p>Secondly, I am struggling in the Bio class. I have not taken AP Bio and I don't understand what is going on in the class. They teach as if you already too AP Bio. I took bio in 9th grade and passed with a C. I don't remember much and just know some basic concepts I have learned in my Anatomy & Physiology class such as the break down of the cell and the structure of the heart and how it functions. Again, could you suggest me a book I can purchase that will teach me everything I need to know for the Bio subject test?</p>
