When you register your account, you will receive 20 points automatically. Above that, you can get an additional 10 points for confirming your email and 5 points for every day you log in to Brainly.
But there is an even better way to earn points: answering questions! Every time you post a great answer, you will receive 50% of the points that were allocated to that question. Write a particularly awesome answer and you might also be awarded the Brainliest Answer, giving you an additional 25% of the points pool!
Moderators also receive 5 points per moderation action performed, such as deleting bad content, asking for a correction, or approving a question or an answer.
