im so sad i literally cried for 10 min straight because i have three 70's on my grade progress report and my mom only wants 80's
givi [52]

Answer:

You shouldn't blame your mom. You are more than capable of getting 80's that is the bare minimum. Your mom does not want you to fail, try harder and get better grades. 70's are not the best
