6 Hours of summer school?

Help me my mom is making me go to summer school 6 hours a day for the next 14 days. The school only has 2 classes 3 hours for math and 3 hours for english no breaks just intense hard working. They give you a test and give you worksheets in a full class. Please I didn’t do bad in either math nor english I just need to brush up on some of my skills. Please tell me some ways to convince my mom that this is way it intense and uneeded?
