When teaching in-person classes at the students' place of work, every effort is made to be as paperless as possible; students get soft copies of relevant material, e.g. course books, & handouts.
Equally, homework is sent via Google Classroom or email to our clients who after completing it, send it back to their teacher for correction. This frees up more class time to discuss any errors made as well as giving more time to class discussion and communication.
