On the BI Studio you can find 3 global metrics of the simulations or sessions:
Total of Simulations: corresponds to the number of times the user performed a clinical scenario. It does not correspond to the number of scenarios explored but how many times you have played them, including repetitions.
Correct Answer: percentage of the correct answers to the Multiple Choice Question appearing at the end of the simulation.
Simulation Accuracy: calculated according to the number of successful scenarios you perform within the total of scenarios completed.
Remember that a successful scenario is the sum of successful performance on the clinical scenario and the correct answer to the multiple-choice question.
