how can I check my analytics report questions answer?

I can not upload data files

Confusing Questions:

...... in the most recent month?

What month is it?

I accidentally clicked "Run simulation", so it saved my round1 result. I am really worried about it because I can’t seem to return it. I am really really sorry about that and very anxious I don't know what to do, could you tell me how to figure out this problem? Thank you so much!!!

It would beneficial to provide feedback/correct answers after the round is completed and the due date of the assignment is reached. The video about how to clean data was very brief but not thorough.

To be honest, cleaning files should be left to an excel course, mostly when you ask to clean 6 spreadsheets. This is way too much time consuming, we have a huge workload this week added to our second test.
You give tips on how to calculate 2 questions, but there are issues that could lead to misinterpretation.
Some of your course videos are not available anymore.
Thanks

Replacing a new file - there is no notification stating the change was made

Confused, the Download section states the data that will be on the file, but when you download the file, there are additional columns outside of what is listed. Does that mean that we should NOT clean the additional columns? I deleted them and i was notified that columns were missing.

When looking over the data sets to change dates that not within the Q1 2019 range, where do we find that entire range? I get that it starts 1/01/19, but when exactly does it end for Buhi?

Also, what dates should the incorrect dates be updated to? There seems to be no guidance on that.

The information on my file errors is inaccurate. The row ID number is off by 1.

Download my files that I uploaded. Most importantly on the Analytics page.

Update Guides:

It states:

However, if data is omitted, this should always be noted, with details about what information was changed or removed.

But I have no place to note my changes...

Landing Page files

But how should we deal with what we remove? Leave it blank? Replace with null? Replace with average? What? My inclination is leave it blank, but . . .

Videos should have a transcript for ADA.

On the intro page there are two sections under the intro video, but it isn't clear what they are. At first I thought they were just the text version of the video and ignored it. But then I noticed they didn't follow the video but still weren't mentioned. If these two items aren't tied to the video, I wouldn't keep them on the same page. I think most students will ignore them.

Organize Excel tutorials - it's hard to know which one will teach me what I am trying to learn and I'd rather not look at them all unless I know I need to.
It would also be nice to have Excel tutorials next to the tasks we have to complete. Maybe students in this class will already know how to do what we are asking, but it would be nice to have a tutorial or 2 next to each task in the first round to get comfortable.

There really isn't a clear way of knowing what decisions have been completed.

The upload the Search Traffic will not upload my .csv I've made sure multiple times that it is a .csv and it says that it is still an invalid file type.
