...asked more evidence in the competencies 1 to 4 and 8. I wrote 400 pages...
Just wanted to make a quick comment.
Hope, I do get this right, but I thought, if they ask you for more evidence, they mean "hard core" evidence, e.g. course certificates, curriculum, peer reviews, performance appraisals etc., not more of your own writing/ reflections. ???

And as to 8/research: normally, all you have to do is submit your curriculum and research project.

Hope this helps,
