What is the easiest way to get a good grade on a final for 7th grade middle school. I am really worried I won't do well on my science one because it is over everything we learned in that year. The final is tomorrow and I am so worried cause if I get any Bs then I am grounded. I have all As now and I can't afford to get a bad grade.

look back at your notes and old lessons from the year if you have them. And looking up a science videos could be beneficial. don't try and stay up super late and try and gather so much information, you'll most likely be tired and forget it all anyway. Flashcards are great study tools as well.
