Free enrollments
September 2026 — 37 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.
28 practice-test courses and 9 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 Oct 4, 2026. Codes can run out before their date — if checkout shows a price, that one is gone.
