Don't worry if you didn't do Paper 3 and see a 0 in that spot; it doesn't mean anything, since only the top 2 papers in that category will count. Angel requires that a numerical grade be listed, so that's why there might be a zero there.
The same holds true for other grades, too, where the lowest grade in the category will be dropped; a zero (if something is optional) is just a placeholder. It does not mean that you were penalized for not doing the blog option instead of the report or vice versa.
I haven't posted the report grades yet, but the other grades we've completed thus far should be in Angel.
Do NOT rely on Angel's calculations. As I mentioned in a previous post, sometimes it's impossible to get it to recognize the correct number of total points, as with the precis.
