I would suggest staying after school, or even just talking to your teacher whenever you get the chance. If anything, they love to hear students speak up whenever they are confused or having a hard time with things. If you’re kinda scared of your teacher (some teachers aren’t as approachable as others), I would first seek another algebra I teacher if your school has multiple (mine does) or another student to tutor you. Online resources are best, but don’t be scared to look back into the book every now and again. Practice problems are key. Also, I can’t emphasize how important it is to speak up when you have a question. Other students might sigh every now and again but TRUST ME, I flew through Algebra, am currently taking honors algebra II, and we are thankful when somebody has a question. Put in the time, and you’ll get the results in return. If all else fails, seek an adult tutor to come to your house and help you. If can really get you that one on one time.
Sincerely,
Distressed high schooler
