This can also be deleted upon written request); and (iii) demographic data (such as a customer’s zip code, age and income), (iv) scheduling information such as when the best time for a lesson is (v) tutor evaluation information such as quality of tutoring, how you feel your student can improve, what his recent grades are, (vI) practice test and quiz information.
