"Don’t be afraid to ask questions. Don’t be afraid to ask for help when you need it. I do that every day. Asking for help isn’t a sign of weakness, it’s a sign of strength. It shows you have the courage to admit when you don’t know something, and to learn something new. So find an adult you trust – a parent, grandparent or teacher; a coach or counselor – and ask them to help you stay on track to meet your goals."
Barack Obama wants students to ask questions if they don't understand things.
