This project has only one funding source: your donations. The monthly maintenance cost is $100.

Last month I added a new MariaDB database with a preloaded University DB, 9 new questions, and refactored many questions and lessons.

With your support, I plan to continue this work: write new lessons and tasks, and improve existing lessons.

To keep the project running next month, we need to collect at least this amount by the end of this month. Anything above it goes to new lessons, exercises, and features.
