Bowen's 38 episodes are the hottest, and I personally think the score is the best. It is also good to plan a plot every two days. If you want to deepen your ability, it is not recommended to use 38 sets. This is to practice and improve the correct rate. If you want to improve your ability, you can use the school materials, mainly the integration and summary of each question, problem induction, thinking and application. If you have to choose, there are only 5.3 sets and 45 sets of Star. 5.3 is to summarize your knowledge. It is ok to take some time to do it carefully every day. 45 is relatively simple, but the theme is classic. It is a sharp weapon to consolidate while learning, and its research value is higher than 5.3. I suggest you buy all the newspapers Bourne can buy, as well as the 45 sets and the last volume of Star, which is enough. You can also buy a mathematical gold magazine if you have a wheel, but the title is of high quality.

The above is what I think we can learn from. I hope to adopt them.
