Of course it’s possible. In the end there’s no big difference between courses with and without a test. A scorm package must always send the score a user has achieved for the Assignable Unit (AICC_Score). If you don’t have a test you’ll have to set the score manually, if you have a test you can use the test score to fill in AICC_Score. Lectora creates a variable for the test called “Name_of_your_test_chapter_Score”, e.g. “Test_1_Score”.
