In fact, the contents of these books are similar. Just look at the content, as long as there are examples, the analysis is very detailed. What matters is how you use it, whether you can persist and be good at taking notes and summarizing. You can't expect it to contain the original questions of the college entrance examination. The problems are ever-changing, but the essence is only a few. I'm a little wordy, but the real idea is that I'm preparing for the postgraduate entrance examination. Math textbooks are not the best. The key is how you do it! A book, once written, can't be eaten thoroughly, just do it again. Our math review book teacher asked us to do it several times. . .

Success will come naturally. I wish you a smooth college entrance examination ~
