There are 14 units in total. I have done two and passed them. I have done another 3 courses but the tutor has requested corrections for some of the answers. Then there is 8 courses that I am yet to do. I have an answered template from a past student of the course, which you will need to edit to avoid plagiarism, I will submit it to the tutor if any come back for corrections then you will fix that.
So it means you are not staring the work from scratch, just editing and correcting the ones that come back for corrections. The attached file is an example of what the questions and answers look like, just rewording them. In total there will be 12 of such files. With 3 of them already previously submitted and just a few corrections in them.
