I received invitation to test on June 01st with start date June 04th to 24th. I wrote the test on June 06th but here is my concern. As i began after accepting and ticking boxes, took the photo ID for submission, my computer was glitching and acting funny, rolling continuously and not able to progress to personal picture before it timed me out. I requested for another link which was sent to my email but the computer was still rolling before it finally crashed. I logged in to another system, open my email box, used the new link and proceeded to take my photo ID and personal picture for confirmation on the new computer, started the test and submitted smoothly without any glitch or hindrance. I passed with 19/20 within six minutes. Would the system change be a concern?
