How do people consistently get high 90

I get that some people are willing to spend every waking moment on school, and others are just incredibly genius but how do other people get high 90s alongside doing other things? I genuinely just think this would be a useful post to have in this community because everyone probably has different ideas. Please join the brainstorming and share any study strategies, revision techniques, or any other ideas you have. As you never know what will help someone else.
