[header] How to not get called on in class [title] Sit strategically. [step] You want to try to sit in the teacher's blind spot so they hopefully don't notice you. Where you sit depends on the style of your classroom and your teacher. 
Try to sit in the edge of the classroom, out of the teacher's main focus of vision. You can sit in the back to hopefully hide or the very front so the teacher possibly completely looks past you and forgets you are there.
