Udemy has just announced their big €9.99 sale. Ten days, starting today.

The price can be different for some courses and in some regions, but it is simply the lowest possible price; for example “Linear Algebra and Geometry 1” is €11.99, so this is the lowest possible price for this course in the EU; I cannot see the prices in $ here.

If you plan to purchase any of our courses between now and August 27th, please, use our referral links below. It will not make any difference to you, but it will make a big difference to us.

Thank you for your ongoing support for our work!
