Just put them anywhere
Fun Colleague is still on holiday, so I had to teach her Thursday evening course. I've taught it before and know the students, so I'm her permanent substitute (so to speak). It consists of two older ladies, one in her 50s and one in her 60s, both of which are beginners. Today, we had a guest student.The guest student told me that she had called a few days ago and explained to the secretary that she had previously taken lessons at our school and which book she had used - basically telling the secretary which level she belonged in.
Being a top notch secretarial staff, she was scheduled to be in a class for total beginners.
The writing on the guest card? Young Secretary's.
