how can i concentrate more on the work than getting confused.

Answer 1

You don't say what grade but one thing I've done is to read the passage(s) out loud, then a second time if that is necessary. Think about what you are reading while reading out loud, make sure you understand the principles behind the definitions, and work the problems at the end of the chapter. As you learn what helps, put more time in on those things that work and less time on those that are less effective. Don't give up and be disciplined to work every day on the subject, not just when the mood strikes you. Good luck.

Be sure to read the introduction to the student and be sure to go through the lessons carefully and in order! This is not a quick fix. It takes time to unlearn bad habits and establish good ones.

Choose what you need help with; there's a section on science classes, as well as other subject areas and studying and test-taking in general.
