Long rant on my teacher

I swear even after 20 years of teaching, she still hasn't learnt anything?? I'm pretty sure my math teacher doesn't plan out her lessons. She doesn't explain the concepts. She doesn't check our understanding. At this point, she's not even teaching.

When she starts on a new chapter, she jumps straight into it without an introduction. Oh and no time for us students to absorb the information at all. So I'm often confused on what she's teaching. What makes it worse is that there's no effort in helping us understand the topic. She goes straight to the questions. It's literally 95% going through questions and 5% of teaching. We don't even get time to try the questions out. It's so bad that I had to ask GOOGLE to explain certain terms to me during the lesson because she didn't. Isn't it her job?

Anyway, the only way I'm able to maintain my A1 is because I VOLUNTARILY asked for tuition. I never thought I would do this. But for the others who may not be able not afford tuition, they have to struggle in school because of her. One of my classmates who got As for math last year failed this year. That's a very drastic change. She did roughly the same in other subjects this year as she did last year so the problem definitely isn't my classmate. UGHH I'm so frustrated right now. Yes I know teaching is hard but she's not even trying. She's getting paid for her shitty teaching btw 💔
