As an admin, you can merge all the results of online tests and offline tests. In short, you can collect all the results data of students for online exams and offline exams.
Some of the students have taken online exams, and some of the students have taken offline exams. The test is the same for all the students: it’s online mode and offline mode. So, at that time, you can combine the results and share them with students.
If you wish to share combined results, you can, or else you can share individual results. It depends on the admin how he/she wants to share the results.
