2. Practice more basic knowledge and take root at the grassroots level;
3. Do a set of wrong questions, find the wrong places, carefully write down the correct answers in red ink (know how to get them every step), and take them out before each exam. This should be adhered to.
4. Take time to preview before class and review after class; It seems easy, but few people will stick to it.
Finally, learn to encourage yourself. I believe you can do it, and so can you.
I hope I can help you, thank you
