Free enrollments
August 2026 — 30 courses. 100 free enrollments per course, coupon applied automatically at checkout.
Every practice question comes with its own infographic explanation. Not a wall-of-text answer key — an actual diagram of the concept and why the correct answer is correct.
22 practice-test courses and 8 video courses, which are regular training courses rather than question banks . Each code is capped at 100 redemptions and every card shows its own expiry date, the last of them Sep 6, 2026. Codes can run out before their date — if checkout shows a price, that one is gone.
