Looking for Books for Junior High School Study! ! (Over)
My grades started plummeting when I entered junior high school. I obviously learned and knew how to do most of the questions correctly, but I got them wrong when I took the test. Now I am in high school! In the end, I did okay in the exam. Thank you everyone for reading the book (although I didn't read it either). I'll just treat this post as a souvenir.

Friends, Are There Any Novels About Accidentally Breaking into the Tian Family?
Don't push it randomly, it's just a power struggle! It doesn't matter if it's a male channel or a female channel, it needs to be powerful and have that feeling of self-help. If it's a novel I wrote, it's okay to leave a message. I'll read it and leave a message. Okay, thank you everyone
This book is really great! It reminded me of my own experience studying geometry, where I was always confused by the use of auxiliary lines. This book not only shows the thinking process through specific examples, but also provides guidance from a teacher's perspective, allowing me to understand the logic of problem solving. And these thinking methods are not only applicable to geometry, but also helpful in solving other science and engineering problems. I think it is not only suitable for students, but also for people like me who can think and solve problems from different angles when facing problems in life.
