Initially, you start using CoCalc under a free plan. There are various subscription options available to improve the service in various ways. Listed prices are in US dollars (when charging in local currency, the prices are converted into local currency using the conversion rates published by leading financial institutions).
We offer course packages to support teaching using CoCalc. They start right after purchase and last for the indicated period and do not auto-renew. Following this guide, create a course file. Each time you add a student to your course, a project will be automatically created for that student. You can create and distribute assignments, students work on assignments inside their project (where you can see their progress in realtime and answer their questions), and you later collect and grade their assignments, then return them.
Paying is optional, but will ensure that your students have a better experience, network access, and receive priority support. The cost is between $4 and $9 per student, depending on class size and whether you or your students pay. Start right now: you can fully setup your class and add students immediately before you pay us anything!
