This score is normal if you are a senior one, because junior high school and senior high school have different ways of understanding, and there is a gap in knowledge. It takes time to adapt to new thinking. I used to, too. My mother scolded me for failing in the first semester of senior one.

If it's grade two or grade three ... I can only say that you should work harder. In addition to knowledge, the allocation of time for making papers also requires skill.

See, you said you had no motivation. I can only say that it doesn't matter as long as you don't want to learn well or have given up on yourself. Low tide is normal. Even in college, I sometimes don't want to study. But the low tide time should not be too long, especially for high school students. A month at low tide is different from a month at low tide for college students.

In short, don't be nervous. The problem is similar. If you don't require 130+ or 140+, you can practice slowly. If you don't understand the problem, the problem-solving mode will always become your instinct.
