Two thumbs up, and one suggestion
I’m very satisfied with my Ulpan experience. I do have a suggestion, though. Perhaps you could create a space on the website where teachers can list (1) homework for each lesson and (2) the topics to be covered in the next lesson. All of the teachers do this verbally, but some students might find it helpful to see it in writing … in their calendar, perhaps, or some other designated space on their student portal. I’m not sure how many students would need this, but I have noticed that some are more “lost” than others! Perhaps this would help them.
