Don't quit. Try your best to keep both good grades and softball. You can miss or be late to trainings before tests. You can train alone at home instead...more runing and stuff than technique.
You can also miss a few games if you have to study.
Try to explain your coach how school is important to yu as well as the softball.
I hope he'll understand.
Best wishes,
Kathy.
