If you have a teacher you are close to ask if they think you are auditory or visual, whatever one the teacher says will lead you to two conclusions
Visual- you should probably read in a quiet environment and or read the passage multiple times swell
Auditory- you should probably be alone for this aswell and listen to an audios recording of the book and take any notes that you think might help you. Then record your self saying those things and listen to that. You need to be able to stay focused because if you get unfocused the recording will become another background noise while you know are focusing on something else.
