 There is no bulk marks download feature in the current lms, even though it seems other blackboard installations can give students this bulk download ability. It relies on a lot of js crap so I ended up using selenium all the way through. Doesn't download styles to save space, you'll have to download the css and js yourself and it has to be absolute because the script makes no effort to make the links relative.

+This one was made for UWA but you may be able to tweak it for your institution (see constants.py).
+
+Just made it able to download the graded results which may contain annotations. Using a really hacky method to do it so it doesn't create a metadata file for it.
+
+## Note:
+* Does not download turnitin reports. You have to click the link manually to the feedback site.
+* Does not download multiple submission attempts - only downloads the last/graded attempt.
+* Check that the default page is the 'all' category for the marks instead of something else like the submitted category. The script should correct this but just to be safe click on all if it isn't already
