Practice on real problems
Every course comes with practice tests that show where you stand, and problem-driven workflows taken from real people and businesses: their problem, how it was evaluated, the solution and the results. Follow the same steps on your own case.
How practice works
Test it. Then do it.
Tests and workflows belong to the lessons they practice, so you meet them right when they help.
Practice tests
Questions drawn at random in a new order each time, some of them reading a value off a graph. You see your score, a short explanation for every answer and a short reason why each wrong option is wrong. Anyone can take them, no account needed.
Problem-driven workflows
A real case: background, the problem, how it was evaluated, what went wrong, what was missing, what to do, and the results. You start the same workflow on your own case, tick off each step as you do it, log your result and tell us how it worked.
