Yeah I understand. I agree that the thought process behind the answer is more important than the physical act of writing (although that has value as well, especially if exam is near). So what I am doing is actually in between what you do and proper answer writing. I type my answers on Insights. It takes just a little more time than thinking and there is no friction of scanning and uploading. Also, others can review your answers and you also have a record of all your answers.
