$3_{?}$ In an Educational Testing Service $($ETS$)$ management system, various modules and interactions

would be essential to handle the testing processes. Here's a scenario depicting a similar flow for

an ETS management system:

The Test Process Handler Module orchestrates the flow of operations for managing and

administering tests within the ETS system. The Get Test Details Module accepts a test ID and

retrieves details such as test name, duration, subjects covered, and instructions. The

Authentication System Module validates the test$-$taker's credentials before starting the test

whereas the Check Test Eligibility Module validates the test$-$taker's eligibility to take the test

based on criteria such as prerequisites or qualifications. The Test Block Status Module verifies the

test$-$taker's account status and returns a void flag if there are no blocks or issues. The Calculate

Available Time Module determines the available time for the test based on the test duration and

any time restrictions. The Test Administration Module handles the test$-$taking interface,

displaying questions, accepting answers, and managing the testing environment. The Test

Submission Module receives the completed test from the test$-$taker and initiates the submission

process. The Test Evaluation Module evaluates the submitted test, calculates scores, and

generates result reports.The Result Processing Module processes test results, generates reports,

and updates the candidate's profile with scores and performance metrics. Lastly, Print Test

Report Module generates a detailed test report for the test$-$taker or institutions upon completion.

Now design a structure chart based on the above scenario.
