More sites that are like Brainly are Quizlet, and Jishka. I trust those two sites along with Brainly.
Quizlet is a studying site where you can find flash cards to study.
Jishka is similar to this site. It has homework questions that you can ask. Note: there are some ppl who like to give the incorrect answers to your questions.
