Hello Allen
I want to ask about final test.
Is it available to upload PDF  file for test? For mid-term exam I sumitted some pictures and flash cards on the lesson plan.  But pictures disppeared and I  just found severeal *** . For lesson plan, flash cards, pictures and diagram are important. If not, I should write all what I want to speak. Sometimes visual thinking meterials are much more effect. I am curious that I may upload PDF lesson plan.
