Very helpful for core basics to get started

The first two weeks are a good introduction to Aggregation and what you can do with it. The third week is more focused on using Mongo in machine learning applications and teaches you less new Mongo content and isn't in depth enough to be a good introduction to machine learning, but is a good way to get familiar with using the tools you've been shown earlier in the course. Some of the exercises are a little unclear in their wording but the course administrators are quick to reply in the forums and they update the workbooks in response to feedback. Overall would recommend to anyone who will be using Mongo and wants to get an overview of it's capabilities and some practise putting it into action.

Overall a good course. Some of the labs could be more intuitive and in one (I gave some feedback in the comments) has IMHO so false datasource. I also think that especially in Week3 some labs have to much information given and the student only has to do some minor tasks.
