A five-day learning journey for making better decisions when outcomes are uncertain, information is incomplete, probabilities are imperfect, and the consequences of being wrong matter.
Across 5 days, five a day — about 30 minutes each.
Scored, one attempt each. No retries — so the score is real.
A Learn50 Score out of 100 and a Tier, from Copper to Diamond.
A verified Certificate from Learn50, at 40% and above — for your CV and LinkedIn.
Every module ends in something quantified and slightly surprising — a number you did not expect, worked out in front of you. Nothing here asks you to memorise a term.
Locked the moment you answer. No retries, no second attempts, no grinding a score upward. That is exactly why the score is worth putting on a CV.
5 modules a day across 5 days. Built for people with a job, on a phone, in the gaps — not for people with a free afternoon.
Paid once. No subscription, no expiry, and no upsell at the end. The same rate applies whichever Learn50 course you start with.
At 40% and above you get a certificate that is a web address, not a file. Whoever you send it to opens it and sees the same score, date and number you do.
No degree, no entrance test, no application. Every term is defined the first time it is used, and nothing assumes you studied this before.
There is no file to lose and nothing to forge. The certificate is a web address, and whoever you send it to sees the same score, the same date and the same number that you do.
