How long will I have access?

You’ll have access to the course materials for 8 weeks from the time of enrollment. This timeframe is designed to help you stay focused, make consistent progress, and finish strong — without dragging things out.

Is the course self-paced?

Yes — both courses are fully self-paced within your 8-week access window. You can move through the lessons on your own schedule and revisit materials as often as you’d like during that time.

What if I fall behind?

Life happens. If you need a short extension due to unforeseen circumstances, you can email Dianna directly to request additional time. We want you to succeed, not stress.

Are these courses for beginners?

Absolutely!

The Excel Mastery course is designed for professionals who are self-taught, who never had proper training or simply need a refresh. It starts with foundational tools and builds toward more advanced skills in a clear, structured way.

Power of Excel assumes a basic comfort level with Excel (specifically lookups and pivot tables) and dives into specialized tools like Power Query, Power Pivot, and Power BI — but everything is broken down step by step.

Do I need specific software?

You’ll need access to Microsoft Excel (desktop version).

For Power of Excel, you’ll also need the Windows version of Excel with access to Power Query and Power Pivot features. Power BI Desktop is free to download and will be used in one module.

Do I get a certificate?

Yes! You’ll receive a certificate of completion when you complete all course modules.

Is there a refund policy?

Because this is a digital course with immediate access to materials, refunds are not offered.

We recommend reviewing the course overview and reaching out with questions before enrolling to make sure it's the right fit for you.
