We recommend bringing a friend who is also studying the same subject, of course!
Aside from that, you're welcome to bring anyone. For younger students, this might be a playdate or a family friend. For high schoolers, this could be your best mate . Ultimately, make sure you invite someone you get along well with, have similar goals, and most importantly, want to learn!
Your tutor will involve both of you in the learning process and make lessons as interactive as possible.
