Simplifying MYP Tests

I've been working with the MYP for around a year and a half now and so far I've found that for the most part it aligns very well with my own teaching philosophy. But that's not to say that the process of working within the framework is always straightforward. For me this has been most apparent when designing and grading MYP assessments. I'm completely on board with the philosophy, but often have trouble with the particulars. After finally wrapping my head around Criterion B and C assessments I decided to turn my attention to Criterion A. Like many teachers, I have previously worked in a system where tests were based on percentages and while I would make every effort to include problem solving and information interpretation questions, it was never specifically required. For me this made the process of designing and particularly grading an MYP test quite challenging. After a lot of consideration I decided that the best way to approach writing MYP tests would be to write a test as I normally would, but then have a system set up to track the achievement levels and strands addressed, and subsequently the performance of students on each question. At first I thought about learning to design a program to perform that task, but realised that if I designed it in Google Sheets I could use Google Classroom to distribute copies to students. So after locking myself away for a full Saturday, this is what I've come up with. It's only the first version and may have some bugs, but let me know if you think this could be a useful tool. Just save a copy to your own Google Drive and start planning a test.
