What research says
Testing beats restudying
Roediger and Karpicke (2006) found that, a week later, students who had taken a test remembered more than students who had reread the material.

In Karpicke and Roediger (2008), repeated retrieval produced large gains in long-term memory. Repeated study did not produce those gains.

Two meta-analyses found the testing effect in a wide range of settings (Rowland, 2014; Adesope et al., 2017).

Showing learners the correct answer after a quiz helps them correct their mistakes and increases the benefits of testing (Butler and Roediger, 2008).
doi:10.3758/MC.36.3.604How we apply it
Quizzes put your knowledge into a client conversation. For example: 'A client asks about a developer handover date. What do you say?' You get immediate feedback, including the correct answer and why it matters on a sales call.
FAQ
Is a quiz a test of my performance?
No. Quizzes in coachroom.ai are designed for learning. A wrong answer gives you something to revisit and practise.
