Pay attention to the key points in class.
Don't be busy taking notes, listen to the teacher first and get to know the idea. If you don't understand something, write it down as a key point and ask your classmates or teachers after class.
Writing is the key.
Only by solving problems independently can we truly master knowledge. Take time to do some problems every day. If you can solve them smoothly, you have made progress.
Understanding is the most important thing.
Write down what you don't understand in the book and ask the teacher in time. Every concept should be deeply understood, especially function and geometry.
Function is the key.
In junior high school, function is the key. With the deepening of learning, geometry may become more and more difficult, but functions are always based on understanding.
Believe in yourself, come on!
Remember, you have enough time and opportunities, believe in yourself, come on! I hope my experience can help you.
