[[!template text="""would be to use Excel or LibreOffice""" start="00:00:15.080" video="mainVideo-table" id="subtitle"]]
[[!template text="""for doing that.""" start="00:00:17.720" video="mainVideo-table" id="subtitle"]]
[[!template text="""However, I think that approaching it from Emacs""" start="00:00:18.600" video="mainVideo-table" id="subtitle"]]
[[!template text="""has several interesting advantages.""" start="00:00:21.180" video="mainVideo-table" id="subtitle"]]
[[!template text="""First, I would like to write the qualification""" start="00:00:24.480" video="mainVideo-table" id="subtitle"]]
[[!template text="""next to the justification, next to the student error,""" start="00:00:27.660" video="mainVideo-table" id="subtitle"]]

[[!template text="""Actually, I always prefer to write in Emacs""" start="00:00:36.640" video="mainVideo-table" id="subtitle"]]
[[!template text="""for many reasons, as many of you.""" start="00:00:38.840" video="mainVideo-table" id="subtitle"]]
[[!template text="""Also, I love text format because I can compare versions""" start="00:00:42.720" video="mainVideo-table" id="subtitle"]]
[[!template text="""using a control version system like Git and easily change.""" start="00:00:46.680" video="mainVideo-table" id="subtitle"]]
[[!template text="""This is very useful for the revision period""" start="00:00:50.280" video="mainVideo-table" id="subtitle"]]

[[!template text="""I also can export the results directly to PDF""" start="00:01:01.040" video="mainVideo-table" id="subtitle"]]

[[!template text="""I have many tools for doing that.""" start="00:01:08.680" video="mainVideo-table" id="subtitle"]]
[[!template text="""I already knew about Org-table formula.""" start="00:01:11.360" video="mainVideo-table" id="subtitle"]]
[[!template text="""I thought it was very cool and useful""" start="00:01:13.200" video="mainVideo-table" id="subtitle"]]
[[!template text="""to use Emacs for that,""" start="00:01:15.200" video="mainVideo-table" id="subtitle"]]
[[!template text="""and I have actually found a package `orgtbl-aggregate`""" start="00:01:16.160" video="mainVideo-table" id="subtitle"]]
[[!template text="""that seemed adequate for doing that.""" start="00:01:19.240" video="mainVideo-table" id="subtitle"]]
[[!template text="""Unfortunately, I didn't see a lot of information""" start="00:01:22.860" video="mainVideo-table" id="subtitle"]]
[[!template text="""about how to do that in a painless way.""" start="00:01:26.320" video="mainVideo-table" id="subtitle"]]
[[!template text="""So, I have to learn, training and testing,""" start="00:01:29.160" video="mainVideo-table" id="subtitle"]]

[[!template new="1" text="""Demonstration""" start="00:01:41.960" video="mainVideo-table" id="subtitle"]]

[[!template text="""Well, let's start.""" start="00:01:41.960" video="mainVideo-table" id="subtitle"]]
[[!template text="""First, I have two sections,""" start="00:01:44.800" video="mainVideo-table" id="subtitle"]]

[[!template text="""It's very useful to check with a note.""" start="00:01:57.560" video="mainVideo-table" id="subtitle"]]
[[!template text="""I can go directly using your helm or ivy""" start="00:02:05.440" video="mainVideo-table" id="subtitle"]]
[[!template text="""or consult to go directly to the section.""" start="00:02:10.160" video="mainVideo-table" id="subtitle"]]
[[!template text="""So it's very nice.""" start="00:02:13.000" video="mainVideo-table" id="subtitle"]]
[[!template text="""Then I put the comment, right, completely wrong,""" start="00:02:14.560" video="mainVideo-table" id="subtitle"]]
[[!template text="""it answers other questions.""" start="00:02:22.880" video="mainVideo-table" id="subtitle"]]
[[!template text="""I put other comments here that I could send to the student,""" start="00:02:30.600" video="mainVideo-table" id="subtitle"]]

[[!template text="""I can put the qualification, the score for each student.""" start="00:02:37.481" video="mainVideo-table" id="subtitle"]]
[[!template text="""The thing with that is, initially,""" start="00:02:40.160" video="mainVideo-table" id="subtitle"]]
[[!template text="""when I started doing that, I put, I don't know,""" start="00:02:43.160" video="mainVideo-table" id="subtitle"]]
[[!template text="""the exception and a qualification with that.""" start="00:02:46.220" video="mainVideo-table" id="subtitle"]]
[[!template text="""Okay, that's one point, this a three,""" start="00:02:50.720" video="mainVideo-table" id="subtitle"]]

[[!template text="""Okay, that's nice.""" start="00:03:06.680" video="mainVideo-table" id="subtitle"]]

[[!template new="1" text="""Range""" start="00:03:08.320" video="mainVideo-table" id="subtitle"]]

[[!template text="""But then, when I started getting more and more parts,""" start="00:03:08.320" video="mainVideo-table" id="subtitle"]]
[[!template text="""I considered it more useful to use,""" start="00:03:11.640" video="mainVideo-table" id="subtitle"]]
[[!template text="""to put for each part,""" start="00:03:17.082" video="mainVideo-table" id="subtitle"]]

[[!template text="""the first one is two scores, the second three points,""" start="00:03:25.560" video="mainVideo-table" id="subtitle"]]
[[!template text="""the third one is one point, and the last one, four points.""" start="00:03:28.680" video="mainVideo-table" id="subtitle"]]

[[!template text="""Of course, I have to change the qualification,""" start="00:03:47.320" video="mainVideo-table" id="subtitle"]]
