Excel with ChatGPT, at your own pace
glostatsi teaches Excel the way a lot of spreadsheet work now gets done: you describe the problem to ChatGPT, get a formula back and learn why it works. Six self-paced courses, and every module comes with a practice workbook, a prompt cheat-sheet and a finished file to compare.
example shelf One jar per course. Try it, nothing here is saved to an account.

module · date · course · note
A module is done when the practice workbook is done. Log it with the date, the course it belongs to and a short note, such as whether you compared your sheet with the finished file. It prints on the log and drops into its course jar.
six courses, your own shelf
The six courses run from Formulas & Functions to VBA, Scripts & Macros. The example shelf keeps Power Query and VBA together in one PQ & VBA jar. Add a jar of your own, for a topic you want to revisit or a set of modules you are saving for later, and set how many modules go in it.

a finished workbook, by a date
Projects join the skills up the way they do at work: a monthly sales report built from a raw export, one module at a time. Give it a date, log each module you finish, and slide the pace to see when the workbook is done.

A slip at 75%
On this example shelf a slip prints when a course passes the mark, and a jar is full once every module planned for it is done. Try it:
left out on purpose
Short modules, real workbooks and prompts you can reuse. Some things are simply not part of it.
Certificates
No certificate or badge at the end. What you keep is the workbook you built and the patterns behind it.
Accreditation
The courses are not accredited and do not count towards a qualification.
Instructor access
No tutor or live help inside the courses. The finished file shows you what right looks like.
Unlock schedules
No cohort to wait for and no drip feed. Every module is open from the day your plan starts.
A paid ChatGPT plan
The free tier covers the lessons. The few advanced lessons that mention paid features say so.
