Due to COVID-19 we transitioned the classes to an online format this past spring.  We had a very positive experience with having a Cambridge instructor provide the lessons using WebEx and continued the format for our summer program, which is currently in its third week.  We utilized the online diagnostic (or pre-test) to determine the students’ baseline performance and allow for customized instruction and practice.  Students have responded well to the online format.  I recommend it with no reservation.
