Summer sale 2026

Dear students,

We start a summer sale today: you can purchase all our courses for the lowest possible price (valid 5 days, i.e., until July 11) if you use our code:

SUMMER26

(the same for all the courses) at the checkout.

Please, share this message with others; maybe you know some ambitious high-school students who want to be more than prepared for the university, or university students preparing for their tests, or AI/ML professionals in need for some serious basis in math: just tell them about our courses 🙂

Kind regards,

Hania

PS. Here come the links to all our courses, with the code, so you get the discount while purchasing the courses using these links:
