Relaunch

See the bottom of this page - I think you can in any case report the interruption as a mitigating circumstance - see the bottom of the page: https://www.accaglobal.com/an/en/student/exam-entry-and-administration/computer-based-exams/remote-session-exams/on-exam-day/troubleshooting-guidance.html I know my heart would flip if I was bounced out of an exam that was in progress.

Then don't - it's entirely up to you. I say you "can" because de facto you were interrupted by a technical issue, that doesn't mean you have to.

I can't replicate individual student's experiences - I have no reason to launch the exam software. I suggest contact ACCA directly https://www.accaglobal.com/vn/en/footer-toolbar/contact-us.html if it's a nuisance.
