The certificate, honestly
On Alison the course is free; you pay only if you want the certificate or diploma at the end. That credential purchase is where Prepping Bargains earns an affiliate commission — so we flag a diploma only where it’s genuinely the better pick for someone going deep, never just because it pays more. Take the course free and skip the certificate, and that’s a perfectly good outcome.
Free to take. Any certificates or products are optional and paid — if you buy one through our links, PB earns a small commission at no cost to you. Details: /disclaimer
