you are a mathematics teacher right? i have a few questions.. i have problems uploading picture files.. when i uploaded the file in both site files and files, the moment i go and edit the quiz the image section will have something saying "no image have been uploaded to your course". for calculated questions, the correct answer formula is the formula used to solve the question or the answer. can you let me have a sample view of your moodle website. can i categorise the questions bank in terms of level of education, subject, and difficultY?
