Not very practical. I am also a student of the 20 13 college entrance examination. If you have a poor foundation, I suggest you do so. Step 1: study the textbook carefully. First, make sure that the textbook is thoroughly understood and that 100% of the questions in the textbook can be done. The second supplement: it is more appropriate to buy a set of "three-year college entrance examination two-year simulation". I hope it helps you.
