Hi Ying,
Thanks for sharing your pitch! For the A/R question recognition, have you thought about how the question will be recognized? I recently came across this presentation: https://youtu.be/NcbQ2UK69Tc – and as I watched your pitch, figured that you’d appreciate the coverage. In the video (covering experiences at a university in Australia), they ended up putting QR codes beside each of the questions, to make it easy for recognizing each question individually. I was also curious about your thoughts on where/how you would source content for your product? Will the content be created by your company? Submitted by teachers? Or perhaps acquired from OERs or other open content sources (such as OpenStax – https://openstax.org)?
