QUESTIONS
Frequently asked
Is this a printed book?
No. This is a digital PDF download. Nothing is shipped.
What may I do with the PDF?
Your purchase covers use within one household or one classroom. You may print replacement copies for that use, but you may not redistribute, upload, or resell the file.
How are the practice sets organized?
Each Volume I workbook follows a focused progression. Skills are sequenced deliberately, with repetition where it helps build fluency, and every answer is verified.
Can I download my workbook again later?
Yes. After payment, the purchase-complete page saves the workbook under My downloads on that browser for one year. Each repeat download is rechecked with Stripe. Save the purchase-complete page if you may need the file on another device.
What if the file has a problem?
Use the support contact shown on your Stripe payment receipt. Defective files and duplicate charges will be corrected.
