Our university conducted exams via this platform. For android users there was a dedicated app(Though many still used chrome browser) and iOS users had to access it via Safari browser. Those using PC/Laptop had to give their exam via the link on either Chrome or Firefox. And yes, it wasn't proctored for us. The only thing we needed to be careful about was, to not navigate away from the screen and if you did, you would be given a warning to a maximum of 30. That too was crazy because even if you navigated only once, it would show 4 instead of one warning. So I don't know if they have fixed this but that shouldn't be problem for y'all. But at times it's really buggy and freezes at any point of time. Though when this happens, the timer stops and resumes once it's working so no need to panic. I had a strong internet connection but still it used to show network error from my side. And because of that, I had to give a re-exam for the same an hour later on the same day. We also had two or three questions being repeated. There was this question I had to answer but the options were in 4 digit number rather than the possible answers. So yes, I had to skip it. But for the remaining part, it went pretty smooth for me. Best of luck dude :)
