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

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.

Be sure to do all the assessment sections first; then go into the sections below that.

in science you might remeber more because you can write it i index cards or find out a way easy for you.

Part of the problem is probably due to your study methods...or lack of them. These sites might be handy.

Although all of these suggestions may not apply to you, most of them should be helpful.

I hope this helps a little more. Thanks for asking.

To concentrate more on work and avoid getting confused, there are several strategies you can try:

1. Create a clear and organized workspace: Start by decluttering your physical and digital space. Remove any distractions that can steal your attention and disrupt your focus. Keep your work materials, files, and tools neat and easily accessible.

2. Set specific goals and prioritize tasks: Break down your work into manageable tasks and set clear goals for each. Prioritize these tasks based on their importance and urgency. This will help you stay focused on what needs to be done, reducing confusion and decision fatigue.

3. Develop a routine: Establishing a consistent work routine helps train your brain to focus and concentrate during specific times. Designate regular working hours, take short breaks in between focused work sessions, and establish rituals or habits that signal your brain it's time to concentrate.

4. Minimize distractions: Identify and minimize distractions that can hinder your concentration. Turn off notifications on your devices, close unnecessary tabs or applications on your computer, and let those around you know that you need uninterrupted time to work.

5. Practice mindfulness and relaxation techniques: Incorporate mindfulness exercises and relaxation techniques into your routine to improve your ability to concentrate. This can include deep breathing exercises, meditation, or taking short walks during breaks to clear your mind.

6. Use time-blocking techniques: Allocate specific blocks of time for different tasks or activities. For example, you might dedicate one hour in the morning for focused work on a particular project, followed by checking emails and attending meetings later in the day. This helps create structure and prevents tasks from overlapping and causing confusion.

7. Break complex tasks into smaller steps: When faced with complex or overwhelming tasks, break them down into smaller, more manageable steps. This way, you can focus on one step at a time, reducing confusion and increasing productivity.

8. Take care of your physical and mental well-being: Ensure you are getting enough sleep, eating well, and staying hydrated. Engaging in regular exercise and managing stress levels also contribute to improved concentration and focus.

Remember, concentration is a skill that can be developed with practice. It may take some time to establish new habits and find the techniques that work best for you, so be patient and persistent in implementing these strategies.
