Hello,

Your answer would be:

1. It’s important to have a good study skill so you can be ready to take a quiz such as world history.

2. It’s important to know your time on tasks because you don’t want to spend all day on one simple task you want to get things done.

3. A schedule can help you get organzied because it helps you with your time such as this go along with your second question.

Have a nice day :)
