I do face-to-face tutoring by appointment at my office (SDSU students click here). This is the only way I can ensure that the student is truly understanding the material. Each session is 55 minutes long (5 minutes to converse with parents, give suggestions or resources, etc.). Every session is charged and limited to two hours maximum (this keeps the student from burning out).
I create personalized lesson videos for each student. I also give each student a private channel to access all of their lesson videos at no additional cost.
The student should be ready for the session:
have questions ready
bring practice problems or homework that they have struggled with
