Questions

Is this the official course material?

No. It is an independent study tool made by a student, and it is not connected to any university. The lessons and questions are written for this site.

Does it work on my phone?

Yes. Your progress is saved to your account, so you can start on your laptop and carry on in the train.

Can I share my account?

One account works in one place at a time. Logging in somewhere else logs out the other device.

Do I need a calculator?

For the theory lessons, no. The Sprint has a no-calculator mode and a mode with exam-size numbers and a built-in calculator.
