If the foundation is good, it is recommended to use a series of "experimental classes", both physics and mathematics can be used. The topic of "Experimental Class" is very good and comprehensive. All the knowledge points you have learned can be involved in the topic, which is not intuitive and clear at a glance, but it needs comprehensive thinking, so a good foundation is more suitable. Don't do it if you have a poor foundation, which will dampen your enthusiasm for learning. If the foundation is general, it is recommended to use "one-stop". This book has many basic exercises and is suitable for students with average grades and basic knowledge.
