I am very sorry to hear about your sister, my sincere condolences to you and your family.
I am not sure that I will be able to change the time to as early as 3 o'clock. Since I last saw you I have added some more students and don't finish at Ladprao 87 until around 4:30.
As for the additional students, I do have many tests available but it may be best to meet them first to see what level their English is at.
I don't think you have many hours outstanding with Active English, I think less than 10 now.
