Ganesha HV:
Couple of points I would like to emphasise:
- Try to avoid using your company-issued laptop as you might land up in lot of issues with the streams not being visible to the proctor. In my case, there was a delay of about 40 mins for this issue. The proctor was unable to see my feed. He asked me to try with a different browser. Tried restart of the devices too. Nothing helped. Finally, he asked me to try with my personal device. I had a desktop running Ubuntu20.04 and things started working fine. I was lucky enough to get a proctor who was reasonable and had quite a lot of patience.
- Be very, very careful and read thru the entire question for the correct names and namespaces in particular.
- Practice the lightning labs and mock exams. Give a break before trying them out so that the questions are erased from your mind before attempting it afresh.
