You can access all your performance information by going to the left side menu of the platform and selecting Analysis > Study Summary.
In this section, you can check the number of completed questions for your Study Objective, along with a summary of your performance and time spent answering questions.
You will also find two charts under the section titled "Study Objective" that can help you track your progress and compare your results over time. These charts include the percentage of questions you have answered correctly (and with help), and details on your answered questions for your current Study Objective.
The Latest Answer tab only includes the percentage of correct answers for your latest attempt on each individual question, while the Overall one takes into consideration all your answers for your Study Objective, including questions answered multiple times.
