1: Familiar with mathematics. Know math. Look at learning correctly and look at teachers correctly.
2. Do more questions. Why are you sleepy? Because you can't. Sleepiness is not caused by your disinterest, but by you. If you want to do it, choose what you have done first. Go to the teacher and ask him or her to help you find some typical problems. Otherwise, you can make an example. Organize a special math problem book. Summarize mistakes, problems and examples. Once you are familiar with math, you won't be sleepy. That's how I fell in love with math. My grades changed from failing to entering the top three in my class. I have been making such efforts since my third year of high school. What about you? You have enough time. You can totally catch up. )

4. Talk more in class! As before, don't be afraid of losing face when you are wrong. You have a lot of meat. What are you afraid of? If the answer is right, how happy it would be.
