This course soured my entire experience with the rest of the specialization.
The instruction on the actual case study is lacking at best, abysmal at worst. Even on the guided questions I was lost with very little direction, and the direction I did get seemed like it was for something else entirely.
What they should have done was give you two optional courses, one for the guided case study and one for the free case study. From there it can allow the instructor to go into more depth about what you needed to do.
What it actually did was give you two modules in the same week, both with vague checklists, and instructions that don't take the actual data you're working with into account.
For example: the bicycle dataset. They give you YEARS worth of data, going all the way back to 2004, and only want you to use about 12 months worth of it. They want you to use google sheets, R studio, or SQL for this. Well google sheets literally cannot handle that amount of data and you will frequently run out of RAM in R Studio UNLESS you upgrade to a full account, because the dataset is just so large. And uploading it to BigQuery literally required me to upload it to google drive first, and then give it a URI because the files were so massive. But one of the steps REQUIRES you to import it into google sheets.
The issue is that this course doesn't make you do case studies beforehand, it gives you bits and pieces of each part of a case study before throwing you out into sea and making you put all of it together yourself with no rhyme or reason. And it doesn't help you can clearly tell that each course was designed by someone different, which I was willing to put up with until this course assumed so much of the past few courses.
Is this course worth it? Yes, you still learn valuable insights on R, Tableau, SQL, Spreadsheets. But don't expect this to be your sole ticket into becoming a data analyst. Manage your expectations before starting.
