So your parent hasn't joined you on the Brainly express to Achievement-ville. We'll get them on board. Parents are busy people, but you can be the boss and remind them. Remind them how Brainly boosts you with expert knowledge. Remind them that tons of students already get grade upgrades with Brainly Plus. Remind your parent of the power they have to raise you to your full potential. We think they would agree. You deserve every education advantage.
